    A compressed full-text self-index represents a text in a compressed form and still answers queries efficiently. This represents a significant advancement over the (full-)text indexing techniques of the previous decade, whose indexes required several times the size of the text. Although it is relatively new, this algorithmic technology has matured up to a point where theoretical research is giving way

    Clinical text, such as clinical trial eligibility criteria, is largely underused in state-of-the-art medical search engines due to difficulties of accurate parsing. This paper proposes a novel methodology to derive a semantic index for clinical eligibility documents based on a controlled vocabulary of frequent tags, which are automatically mined from the text. We applied this method to eligibility criteria on ClinicalTrials.gov and report that frequent tags (1) define an effective and efficient index of clinical trials and (2) are unlikely to grow radically when the repository increases. We proposed to apply the semantic index to filter clinical trial search results and we concluded that frequent tags reduce the result space more efficiently than an uncontrolled set of UMLS concepts. Overall, unsupervised mining of frequent tags from clinical text leads to an effective semantic index for the clinical eligibility documents and promotes their computational reuse. PMID:24036004

    This paper describes MetaIndex, an automatic indexing program that creates symbolic representations of documents for the purpose of document retrieval. MetaIndex uses a simple transition network parser to recognize a language that is derived from the set of main concepts in the Unified Medical Language System Metathesaurus (Meta-1). MetaIndex uses a hierarchy of medical concepts, also derived from Meta-1, to represent the content of documents. The goal of this approach is to improve document retrieval performance by better representation of documents. An evaluation method is described, and the performance of MetaIndex on the task of indexing the Slice of Life medical image collection is reported. PMID:1807564

    The current proliferation of on-line information resources underscores the requirement for the ability to index collections of information and search and retrieve them in a convenient manner. This study develops criteria for analytically comparing the index and search engines and presents results for a number of freely available search engines. A product of this research is a toolkit capable of automatically indexing, searching, and extracting performance statistics from each of the focused search engines. This toolkit is highly configurable and has the ability to run these benchmark tests against other engines as well. Results demonstrate that the tested search engines can be grouped into two levels. Level one engines are efficient on small to medium sized data collections, but show weaknesses when used for collections 100MB or larger. Level two search engines are recommended for data collections up to and beyond 100MB.

    Clinicians have traditionally documented patient data using natural language text. With the increasing prevalence of computer systems in health care, an increasing amount of medical record text will be stored electronically. However, for such textual documents to be indexed, shared, and processed adequately by computers, it will be important to be able to identify concepts in the documents using a common medical terminology. Automated methods for extracting concepts in a standard terminology would enhance retrieval and analysis of medical record data. This paper discusses a method for extracting concepts from medical record documents using the medical terminology SNOMED-III (Systematized Nomenclature of Human and Veterinary Medicine, Version III). The technique employs a linear least squares fit that maps training set phrases to SNOMED concepts. This mapping can be used for unknown text inputs in the same domain as the training set to predict SNOMED concepts that are contained in the document. We have implemented the method in the domain of congestive heart failure for history and physical exam texts. Our system has a reasonable response time. We tested the system over a range of thresholds. The system performed with 90% sensitivity and 83% specificity at the lowest threshold, and 42% sensitivity and 99.9% specificity at the highest threshold. PMID:7949915

  13. Terminology extraction from medical texts in Polish

    PubMed Central

    2014-01-01

    Background Hospital documents contain free text describing the most important facts relating to patients and their illnesses. These documents are written in specific language containing medical terminology related to hospital treatment. Their automatic processing can help in verifying the consistency of hospital documentation and obtaining statistical data. To perform this task we need information on the phrases we are looking for. At the moment, clinical Polish resources are sparse. The existing terminologies, such as Polish Medical Subject Headings (MeSH), do not provide sufficient coverage for clinical tasks. It would be helpful therefore if it were possible to automatically prepare, on the basis of a data sample, an initial set of terms which, after manual verification, could be used for the purpose of information extraction. Results Using a combination of linguistic and statistical methods for processing over 1200 children hospital discharge records, we obtained a list of single and multiword terms used in hospital discharge documents written in Polish. The phrases are ordered according to their presumed importance in domain texts measured by the frequency of use of a phrase and the variety of its contexts. The evaluation showed that the automatically identified phrases cover about 84% of terms in domain texts. At the top of the ranked list, only 4% out of 400 terms were incorrect while out of the final 200, 20% of expressions were either not domain related or syntactically incorrect. We also observed that 70% of the obtained terms are not included in the Polish MeSH. Conclusions Automatic terminology extraction can give results which are of a quality high enough to be taken as a starting point for building domain related terminological dictionaries or ontologies. This approach can be useful for preparing terminological resources for very specific subdomains for which no relevant terminologies already exist. The evaluation performed showed that none of the tested ranking procedures were able to filter out all improperly constructed noun phrases from the top of the list. Careful choice of noun phrases is crucial to the usefulness of the created terminological resource in applications such as lexicon construction or acquisition of semantic relations from texts.

    Objective To adapt and automate the medication regimen complexity index (MRCI) within the structure of a commercial medication database in the post-acute home care setting. Materials and Methods In phase 1, medication data from 89?645 electronic health records were abstracted to line up with the components of the MRCI: dosage form, dosing frequency, and additional administrative directions. A committee reviewed output to assign index weights and determine necessary adaptations. In phase 2 we examined the face validity of the modified MRCI through analysis of automatic tabulations and descriptive statistics. Results The mean number of medications per patient record was 7.6 (SD 3.8); mean MRCI score was 16.1 (SD 9.0). The number of medications and MRCI were highly associated, but there was a wide range of MRCI scores for each number of medications. Most patients (55%) were taking only oral medications in tablet/capsule form, although 16% had regimens with three or more medications with different routes/forms. The biggest contributor to the MRCI score was dosing frequency (mean 11.9). Over 36% of patients needed to remember two or more special instructions (eg, take on alternate days, dissolve). Discussion Medication complexity can be tabulated through an automated process with some adaptation for local organizational systems. The MRCI provides a more nuanced way of measuring and assessing complexity than a simple medication count. Conclusions An automated MRCI may help to identify patients who are at higher risk of adverse events, and could potentially be used in research and clinical decision support to improve medication management and patient outcomes.

  16. On Entropy-Compressed Text Indexing in External Memory

    Hon, Wing-Kai; Shah, Rahul; Thankachan, Sharma V.; Vitter, Jeffrey Scott

    A new trend in the field of pattern matching is to design indexing data structures which take space very close to that required by the indexed text (in entropy-compressed form) and also simultaneously achieve good query performance. Two popular indexes, namely the FM-index [Ferragina and Manzini, 2005] and the CSA [Grossi and Vitter 2005], achieve this goal by exploiting the Burrows-Wheeler transform (BWT) [Burrows and Wheeler, 1994]. However, due to the intricate permutation structure of BWT, no locality of reference can be guaranteed when we perform pattern matching with these indexes. Chien et al. [2008] gave an alternative text index which is based on sparsifying the traditional suffix tree and maintaining an auxiliary 2-D range query structure. Given a text T of length n drawn from a ?-sized alphabet set, they achieved O(n log?)-bit index for T and showed that this index can preserve locality in pattern matching and hence is amenable to be used in external-memory settings. We improve upon this index and show how to apply entropy compression to reduce index space. Our index takes O(n(H k + 1)) + o(nlog?) bits of space where H k is the kth-order empirical entropy of the text. This is achieved by creating variable length blocks of text using arithmetic coding.

    The Third i2b2 Workshop on Natural Language Processing Challenges for Clinical Records focused on the identification of medications, their dosages, modes (routes) of administration, frequencies, durations, and reasons for administration in discharge summaries. This challenge is referred to as the medication challenge. For the medication challenge, i2b2 released detailed annotation guidelines along with a set of annotated discharge summaries. Twenty teams representing 23 organizations and nine countries participated in the medication challenge. The teams produced rule-based, machine learning, and hybrid systems targeted to the task. Although rule-based systems dominated the top 10, the best performing system was a hybrid. Of all medication-related fields, durations and reasons were the most difficult for all systems to detect. While medications themselves were identified with better than 0.75 F-measure by all of the top 10 systems, the best F-measure for durations and reasons were 0.525 and 0.459, respectively. State-of-the-art natural language processing systems go a long way toward extracting medication names, dosages, modes, and frequencies. However, they are limited in recognizing duration and reason fields and would benefit from future research. PMID:20819854

    2011-03-01

    With the widely use of healthcare information technology in hospitals, the patients' medical records are more and more complex. To transform the text- or image-based medical information into easily understandable and acceptable form for human, we designed and developed an innovation indexing method which can be used to assign an anatomical 3D structure object to every patient visually to store indexes of the patients' basic information, historical examined image information and RIS report information. When a doctor wants to review patient historical records, he or she can first load the anatomical structure object and the view the 3D index of this object using a digital human model tool kit. This prototype system helps doctors to easily and visually obtain the complete historical healthcare status of patients, including large amounts of medical data, and quickly locate detailed information, including both reports and images, from medical information systems. In this way, doctors can save time that may be better used to understand information, obtain a more comprehensive understanding of their patients' situations, and provide better healthcare services to patients.

    With the development of electronic systems, privacy has become an important security issue in real-life. In medical systems, privacy of patients' electronic medical records (EMRs) must be fully protected. However, to combine the efficiency and privacy, privacy preserving index is introduced to preserve the privacy, where the EMR can be efficiently accessed by this patient or specific doctor. In the literature, Goh first proposed a secure index scheme with keyword search over encrypted data based on a well-known primitive, Bloom filter. In this paper, we propose a new privacy preserving index scheme, called position index (P-index), with keyword search over the encrypted data. The proposed index scheme is semantically secure against the adaptive chosen keyword attack, and it also provides flexible space, lower false positive rate, and search privacy. Moreover, it does not rely on pairing, a complicate computation, and thus can search over encrypted electronic medical records from the cloud server efficiently. PMID:24158427

    Herskovic, Jorge R.; Cohen, Trevor; Subramanian, Devika; Iyengar, M. Sriram; Smith, Jack W.; Bernstam, Elmer V.

    2011-01-01

    BACKGROUND As the volume of biomedical text increases exponentially, automatic indexing becomes increasingly important. However, existing approaches do not distinguish central (or core) concepts from concepts that were mentioned in passing. We focus on the problem of indexing MEDLINE records, a process that is currently performed by highly-trained humans at the National Library of Medicine (NLM). NLM indexers are assisted by a system called the Medical Text Indexer (MTI) that suggests candidate indexing terms. OBJECTIVE To improve the ability of MTI to select the core terms in MEDLINE abstracts. These core concepts are deemed to be most important and are designated as “major headings” by MEDLINE indexers. We introduce and evaluate a graph-based indexing methodology called MEDRank that generates concept graphs from biomedical text and then ranks the concepts within these graphs to identify the most important ones. METHODS We insert a MEDRank step into the MTI and compare MTI’s output with and without MEDRank to the MEDLINE indexers’ selected terms for a sample of 11,803 PubMed Central articles. We also tested whether human raters prefer terms generated by the MEDLINE indexers, MTI without MEDRank, and MTI with MEDRank for a sample of 36 PubMed Central articles. RESULTS MEDRank improved recall of major headings designated by 30% over MTI without MEDRank (0.489 vs 0.376). Overall recall was only slightly (6.5%) higher (0.490 vs 0.460) as was F2 (3%, 0.408 vs 0.396). However, overall precision was 3.9% lower (0.268 vs 0.279). Human raters preferred terms generated by MTI with MEDRank over terms generated by MTI without MEDRank (by an average of 1.00 more term per article), and preferred terms generated by MTI with MEDRank and the MEDLINE indexers at the same rate. CONCLUSIONS The addition of MEDRank to MTI significantly improved the retrieval of core concepts in MEDLINE abstracts and more closely matched human expectations compared to MTI without MEDRank. In addition, MEDRank slightly improved overall recall and F2. PMID:21439897

    2011-01-01

    Objective A supervised machine learning approach to discover relations between medical problems, treatments, and tests mentioned in electronic medical records. Materials and methods A single support vector machine classifier was used to identify relations between concepts and to assign their semantic type. Several resources such as Wikipedia, WordNet, General Inquirer, and a relation similarity metric inform the classifier. Results The techniques reported in this paper were evaluated in the 2010 i2b2 Challenge and obtained the highest F1 score for the relation extraction task. When gold standard data for concepts and assertions were available, F1 was 73.7, precision was 72.0, and recall was 75.3. F1 is defined as 2*Precision*Recall/(Precision+Recall). Alternatively, when concepts and assertions were discovered automatically, F1 was 48.4, precision was 57.6, and recall was 41.7. Discussion Although a rich set of features was developed for the classifiers presented in this paper, little knowledge mining was performed from medical ontologies such as those found in UMLS. Future studies should incorporate features extracted from such knowledge sources, which we expect to further improve the results. Moreover, each relation discovery was treated independently. Joint classification of relations may further improve the quality of results. Also, joint learning of the discovery of concepts, assertions, and relations may also improve the results of automatic relation extraction. Conclusion Lexical and contextual features proved to be very important in relation extraction from medical texts. When they are not available to the classifier, the F1 score decreases by 3.7%. In addition, features based on similarity contribute to a decrease of 1.1% when they are not available. PMID:21846787

    Public health officials use syndromic surveillance systems to facilitate early detection and response to infectious disease outbreaks. Emergency department clinical notes are becoming more available for surveillance but present the challenge of accurately extracting concepts from these text data. The purpose of this study was to implement a new system, Emergency Medical Text Classifier (EMT-C), into daily production for syndromic surveillance and evaluate system performance and user satisfaction. The system was designed to meet user preferences for a syndromic classifier that maximized positive predictive value and minimized false positives in order to provide a manageable workload. EMT-C performed better than the baseline system on all metrics and users were slightly more satisfied with it. It is vital to obtain user input and test new systems in the production environment.

    This article describes the Indexing Aid Project for conducting research in the areas of knowledge representation and indexing for information retrieval in order to develop interactive knowledge-based systems for computer-assisted indexing of the periodical medical literature. The system uses an experimental frame-based knowledge representation language, FrameKit, implemented in Franz Lisp. The initial prototype is designed to interact with trained MEDLINE indexers who will be prompted to enter subject terms as slot values in filling in document-specific frame data structures that are derived from the knowledge-base frames. In addition, the automatic application of rules associated with the knowledge-base frames produces a set of Medical Subject Heading (MeSH) keyword indices to the document. Important features of the system are representation of explicit relationships through slots which express the relations; slot values, restrictions, and rules made available by inheritance through "is-a" hierarchies; slot values denoted by functions that retrieve values from other slots; and restrictions on slot values displayable during data entry.

    Duplicate publication is considered unethical. It has several negative impacts. To estimate the frequency and characteristics of duplicate publications in Korean medical journals, we reviewed some portion of Korean journal articles. Among 9,030 articles that are original articles indexed in KoreaMed from January to December 2004, 455 articles (5%) were chosen by random sampling. PubMed, Google scholar, KMbase, and KoreaMed were searched by two librarians. Three authors reviewed titles, abstracts, and full text of index articles and suspected articles independently. Point of disagreement were reconciled by discussion. Criteria for a duplicate publication defined by editors of cardiothoracic journals and International Committee of Medical Journal Editors were used. A total of 455 articles were evaluated, of which 27 (5.93%) index articles were identified with 29 duplicate articles. Among 27 index articles, 1 was quadruple publication and 26 were double publications. Of 29 duplicated articles, 19 were classified as copy, 4 as fragmentation, and 6 as disaggregation. The proportion of duplicate publications in Korean medical journals appears to be higher than expected. Education on publication ethics to researchers is needed. PMID:18303213

    This study evaluated the convergent, discriminant, construct, concurrent and discriminative validity of the Medical Student Wellbeing Index (MSWBI) as well as to evaluate its internal consistency and optimal cut-off total scores to detect at least moderate levels of general psychological distress, stress, anxiety and depression symptoms. A cross sectional study was done on 171 medical students. The MSWBI and DASS-21 were administered and returned immediately upon completion. Confirmatory factor analysis, reliability analysis, ROC analysis and Pearson correlation test were applied to assess psychometric properties of the MSWBI. A total of 168 (98.2%) medical students responded. The goodness of fit indices showed the MSWBI had a good construct (?(2)=6.14, p=0.803, RMSEA<0.001, RMR=0.004, GFI=0.99, AGFI=0.97, CFI=1.00, IFI=1.02, TLI=1.04). The Cronbach's alpha value was 0.69 indicating an acceptable level of internal consistency. Pearson correlation coefficients and ROC analysis suggested each MSWBI's item showed adequate convergent and discriminant validity. Its optimal cut-off scores to detect at least moderate levels of general psychological distress, stress, anxiety, and depression were 1.5, 2.5, 1.5 and 2.5 respectively with sensitivity and specificity ranged from 62 to 80% and the areas under ROC curve ranged from 0.71 to 0.83. This study showed that the MSWBI had good level of psychometric properties. The MSWBI score more than 2 can be considered as having significant psychological distress. The MSWBI is a valid and reliable screening instrument to assess psychological distress of medical students. PMID:23380320

    Mining the free text of electronic medical records (EMR) using natural language processing (NLP) is an effective method of extracting information not always captured in administrative data. We sought to determine if concepts related to homelessness, a non-medical condition, were amenable to extraction from the EMR of Veterans Affairs (VA) medical records. As there were no off-the-shelf products, a lexicon of terms related to homelessness was created. A corpus of free text documents from outpatient encounters was reviewed to create the reference standard for NLP training and testing. V3NLP Framework was used to detect instances of lexical terms and was compared to the reference standard. With a positive predictive value of 77% for extracting relevant concepts, this study demonstrates the feasibility of extracting positively asserted concepts related to homelessness from the free text of medical records.

    Clinical information is often coded using different terminologies, and therefore is not interoperable. Our goal is to develop a general natural language processing (NLP) system, called Medical Text Extraction, Reasoning and Mapping System (MTERMS), which encodes clinical text using different terminologies and simultaneously establishes dynamic mappings between them. MTERMS applies a modular, pipeline approach flowing from a preprocessor, semantic tagger, terminology mapper, context analyzer, and parser to structure inputted clinical notes. Evaluators manually reviewed 30 free-text and 10 structured outpatient clinical notes compared to MTERMS output. MTERMS achieved an overall F-measure of 90.6 and 94.0 for free-text and structured notes respectively for medication and temporal information. The local medication terminology had 83.0% coverage compared to RxNorm’s 98.0% coverage for free-text notes. 61.6% of mappings between the terminologies are exact match. Capture of duration was significantly improved (91.7% vs. 52.5%) from systems in the third i2b2 challenge. PMID:22195230

    2012-01-01

    Background The h-index is a commonly used metric for evaluating the publication performance of researchers. However, in a multidisciplinary field such as medical informatics, interpreting the h-index is a challenge because researchers tend to have diverse home disciplines, ranging from clinical areas to computer science, basic science, and the social sciences, each with different publication performance profiles. Objective To construct a reference standard for interpreting the h-index of medical informatics researchers based on the performance of their peers. Methods Using a sample of authors with articles published over the 5-year period 2006–2011 in the 2 top journals in medical informatics (as determined by impact factor), we computed their h-index using the Scopus database. Percentiles were computed to create a 6-level benchmark, similar in scheme to one used by the US National Science Foundation, and a 10-level benchmark. Results The 2 benchmarks can be used to place medical informatics researchers in an ordered category based on the performance of their peers. A validation exercise mapped the benchmark levels to the ranks of medical informatics academic faculty in the United States. The 10-level benchmark tracked academic rank better (with no ties) and is therefore more suitable for practical use. Conclusions Our 10-level benchmark provides an objective basis to evaluate and compare the publication performance of medical informatics researchers with that of their peers using the h-index.

    With the rapidly growing amount of biomedical literature it becomes increasingly difficult to find relevant information quickly and reliably. In this study we applied the word2vec deep learning toolkit to medical corpora to test its potential for improving the accessibility of medical knowledge. We evaluated the efficiency of word2vec in identifying properties of pharmaceuticals based on mid-sized, unstructured medical text corpora without any additional background knowledge. Properties included relationships to diseases ('may treat') or physiological processes ('has physiological effect'). We evaluated the relationships identified by word2vec through comparison with the National Drug File - Reference Terminology (NDF-RT) ontology. The results of our first evaluation were mixed, but helped us identify further avenues for employing deep learning technologies in medical information retrieval, as well as using them to complement curated knowledge captured in ontologies and taxonomies.

    2015-01-01

    Background Hypertension (HTN) is a major public health concern in the United States, with almost 78 million Americans age 20 years and over suffering from the condition. Moreover, HTN is a key risk factor for health disease and stroke. African Americans disproportionately shoulder the burdens of HTN, with greater prevalence, disease severity, earlier onset, and more HTN-related complications than age-matched whites. Medication adherence for the treatment of HTN is poor, with estimates indicating that only about half of hypertensive patients are adherent to prescribed medication regimens. Although no single intervention for improving medication adherence has emerged as superior to others, text message medication reminders have the potential to help improve medication adherence in African Americans with uncontrolled HTN as mobile phone adoption is very high in this population. Objective The purpose of this two-phased study was to develop (Phase I) and test in a randomized controlled trial (RCT) (Phase II) a text message system, BPMED, to improve the quality of medication management through increasing medication adherence in African Americans with uncontrolled HTN. Methods In Phase I, we recruited 16 target end-users from a primary care clinic, to assist in the development of BPMED through participating in one of three focus groups. Focus groups sought to gain patient perspectives on HTN, medication adherence, mobile phone use, and the use of text messaging to support medication adherence. Potential intervention designs were presented to participants, and feedback on the designs was solicited. In Phase II, we conducted two pilot RCTs to determine the feasibility, acceptability, and preliminary efficacy of BPMED in primary care and emergency department settings. Both pilot studies recruited approximately 60 participants, who were randomized equally between usual care and the BPMED intervention. Results Although data collection is now complete, data analysis from the two pilot RCTs is still ongoing and results are expected in 2015. Conclusions This study was designed to determine preliminary feasibility and acceptability of our approach among African Americans with uncontrolled HTN in primary care and emergency department settings. Results from these studies are of great interest as little work has been done to document the use of text message medication reminders to improve HTN-related outcomes, particularly within underserved urban minorities.

    1993-01-01

    One strategy for machine-aided indexing (MAI) is to provide a concept-level analysis of the textual elements of documents or document abstracts. In such systems, natural-language phrases are analyzed in order to identify and classify concepts related to a particular subject domain. The overall performance of these MAI systems is largely dependent on the quality and comprehensiveness of their knowledge bases. These knowledge bases function to (1) define the relations between a controlled indexing vocabulary and natural language expressions; (2) provide a simple mechanism for disambiguation and the determination of relevancy; and (3) allow the extension of concept-hierarchical structure to all elements of the knowledge file. After a brief description of the NASA Machine-Aided Indexing system, concerns related to the development and maintenance of MAI knowledge bases are discussed. Particular emphasis is given to statistically-based text analysis tools designed to aid the knowledge base developer. One such tool, the Knowledge Base Building (KBB) program, presents the domain expert with a well-filtered list of synonyms and conceptually-related phrases for each thesaurus concept. Another tool, the Knowledge Base Maintenance (KBM) program, functions to identify areas of the knowledge base affected by changes in the conceptual domain (for example, the addition of a new thesaurus term). An alternate use of the KBM as an aid in thesaurus construction is also discussed.

    2012-01-01

    In mobile health (M-health), Short Message Service (SMS) has shown to improve disease related self-management and health service outcomes, leading to enhanced patient care. However, the hard limit on character size for each message limits the full value of exploring SMS communication in health care practices. To overcome this problem and improve the efficiency of clinical workflow, we developed an innovative system, MedTxting (available at http://medtxting.askhermes.org), which is a learning-based but knowledge-rich system that compresses medical texts in a SMS style. Evaluations on clinical questions and discharge summary narratives show that MedTxting can effectively compress medical texts with reasonable readability and noticeable size reduction. Findings in this work reveal potentials of MedTxting to the clinical settings, allowing for real-time and cost-effective communication, such as patient condition reporting, medication consulting, physicians connecting to share expertise to improve point of care.

    2008-01-01

    Nowadays a large amount of health information is available to the public, but medical language is often difficult for lay people to understand. Developing means to make medical information more comprehensible is therefore a real need. In this regard, a useful resource would be a corpus of specialized and lay paraphrases. To this end, we built comparable corpora of specialized and lay texts on which we applied paraphrasing patterns based on anchors of deverbal noun and verb pairs. The results show that the paraphrases were of good quality (71.4% to 94.2% precision) and that this type of paraphrasing was relevant in the context of studying the differences between specialized and lay language. This study also demonstrates that simple paraphrase acquisition methods can also work on texts with a rather small degree of similarity, once similar text segments are detected. PMID:18999095

    We describe an exercise of using Big Data to predict the Michigan Consumer Sentiment Index, a widely used indicator of the state of confidence in the US economy. We carry out the exercise from a pure ex ante perspective. We use the methodology of algorithmic text analysis of an archive of brokers' reports over the period June 2010 through June 2013. The search is directed by the social-psychological theory of agent behaviour, namely conviction narrative theory. We compare one month ahead forecasts generated this way over a 15 month period with the forecasts reported for the consensus predictions of Wall Street economists. The former give much more accurate predictions, getting the direction of change correct on 12 of the 15 occasions compared to only 7 for the consensus predictions. We show that the approach retains significant predictive power even over a four month ahead horizon.

    Getzen, T E

    1992-01-01

    The historical development of price indexes as wage adjustment mechanisms is reviewed, as is the theory of aggregation and methods for dealing with quality and technological change. The construction of the U.S. Bureau of Labor Statistics (BLS) Medical Care Price Index (MCPI) is detailed. ARIMA analysis of the MCPI for the period 1927-1990 indicates that; (i) the MCPI is largely a damped and delayed function of the CPI, with an average lag of 8 months; (ii) medical care prices rose 2-4 percent faster than the all-items CPI since 1950, but not for 1927-1950; (iii) health expenditures are affected primarily by the general CPI, with little independent effect of specifically medical prices. The MCPI is a reliable measure of changes in consumer prices with strong construct validity. However, it was not designed for use as a deflator of medical expenditures, and is misleading when erroneously employed in that unintended role. The price/quantity duality and linear expenditure function which form the basis of Laspeyres price indexes are not applicable to nonconcatenable goods such as insurance or medical care. In these complex transactions, quality dominates quantity, fixed prices are replaced by reimbursement and professional judgement, and the assumption of additive separability required to use the price index as a deflator of health expenditures is not valid.

    2014-01-01

    Extraction of medication information embedded in clinical text is important for research using electronic health records (EHRs). However, most of current medication information extraction systems identify drug and signature entities without mapping them to standard representation. In this study, we introduced the open source Java implementation of MedEx, an existing high-performance medication information extraction system, based on the Unstructured Information Management Architecture (UIMA) framework. In addition, we developed new encoding modules in the MedEx-UIMA system, which mapped an extracted drug name/dose/form to both generalized and specific RxNorm concepts and translated drug frequency information to ISO standard. We processed 826 documents by both systems and verified that MedEx-UIMA and MedEx (the Python version) performed similarly by comparing both results. Using two manually annotated test sets that contained 300 drug entries from medication list and 300 drug entries from narrative reports, the MedEx-UIMA system achieved F-measures of 98.5% and 97.5% respectively for encoding drug names to corresponding RxNorm generic drug ingredients, and F-measures of 85.4% and 88.1% respectively for mapping drug names/dose/form to the most specific RxNorm concepts. It also achieved an F-measure of 90.4% for normalizing frequency information to ISO standard. The open source MedEx-UIMA system is freely available online at http://code.google.com/p/medex-uima/.

    Statistical text mining and natural language processing have been shown to be effective for extracting useful information from medical documents. However, neither technique is effective at extracting the information stored in semi-structure text elements. A prototype system (TagLine) was developed to extract information from the semi-structured text using machine learning and a rule based annotator. Features for the learning machine were suggested by prior work, and by examining text, and selecting attributes that help distinguish classes of text lines. Classes were derived empirically from text and guided by an ontology developed by the VHA’s Consortium for Health Informatics Research (CHIR). Decision trees were evaluated for class predictions on 15,103 lines of text achieved an overall accuracy of 98.5 percent. The class labels applied to the lines were then used for annotating semi-structured text elements. TagLine achieved F-measure over 0.9 for each of the structures, which included tables, slots and fillers. PMID:25954358

    Objectives. To apply modern text-mining methods to identify candidate herbs and formulae for the treatment of diabetic nephropathy. Methods. The method we developed includes three steps: (1) identification of candidate ancient terms; (2) systemic search and assessment of medical records written in classical Chinese; (3) preliminary evaluation of the effect and safety of candidates. Results. Ancient terms Xia Xiao, Shen Xiao, and Xiao Shen were determined as the most likely to correspond with diabetic nephropathy and used in text mining. A total of 80 Chinese formulae for treating conditions congruent with diabetic nephropathy recorded in medical books from Tang Dynasty to Qing Dynasty were collected. Sao si tang (also called Reeling Silk Decoction) was chosen to show the process of preliminary evaluation of the candidates. It had promising potential for development as new agent for the treatment of diabetic nephropathy.

    Objectives. To apply modern text-mining methods to identify candidate herbs and formulae for the treatment of diabetic nephropathy. Methods. The method we developed includes three steps: (1) identification of candidate ancient terms; (2) systemic search and assessment of medical records written in classical Chinese; (3) preliminary evaluation of the effect and safety of candidates. Results. Ancient terms Xia Xiao, Shen Xiao, and Xiao Shen were determined as the most likely to correspond with diabetic nephropathy and used in text mining. A total of 80 Chinese formulae for treating conditions congruent with diabetic nephropathy recorded in medical books from Tang Dynasty to Qing Dynasty were collected. Sao si tang (also called Reeling Silk Decoction) was chosen to show the process of preliminary evaluation of the candidates. It had promising potential for development as new agent for the treatment of diabetic nephropathy. However, further investigations about the safety to patients with renal insufficiency are still needed. Conclusions. The methods developed in this study offer a targeted approach to identifying traditional herbs and/or formulae as candidates for further investigation in the search for new drugs for modern disease. However, more effort is still required to improve our techniques, especially with regard to compound formulae. PMID:24744808

    Electronic medical records (EMRs) has been expected to decrease health professional workload. The NASA Task Load Index has become an important tool for assessing workload in many domains. However, its application in assessing the impact of an EMR on nurse's workload has remained to be explored. In this paper we report the results of a study of workload and we explore the utility of applying the NASA Task Load Index to assess impact of an EMR at the end of its lifecycle on nurses' workload. It was found that mental and temporal demands were the most responsible for the workload. Further work along these lines is recommended. PMID:25676971

    The Internet has now become a major source of health information. The aim of CISMeF is to catalogue and index the main French-speaking sites and documents concerning health. This project was initiated by Rouen University Hospital. Its URL is http://www.chu-rouen.fr/cismef. CISMeF covers all areas of health care and medical sciences, and is indexed both alphabetically and according to subject. It was set up on a Sun workstation under the Sun UNIX operating system and is entirely based on static HTML. By May 1999, the number of sites and documents indexed was already over 6,500, with a mean of 75 new sites added each week. CISMeF is updated via a five-step process: resource collection, filtering, description, classification, and indexing. The Net Scoring criteria are used to assess the quality of health information on the Internet. These criteria concern eight categories: credibility, content, links, design, interactivity, quantitative aspects, ethics and accessibility. CISMeF uses two standard tools to organize information: the MeSH (medical subject heading) thesaurus from the Medline reference database (National Library of Medicine, USA) and the Dublin core metadata format. The sites and documents included in CISMeF are described using the following elements from the Dublin core project: title, author or creator, subject and keywords, description, publisher, date, resource type, format, identifier, and language.

    The combination of incessant advances in sequencing technology producing large amounts of data and innovative bioinformatics approaches, designed to cope with this data flood, has led to new interesting results in the life sciences. Given the magnitude of sequence data to be processed, many bioinformatics tools rely on efficient solutions to a variety of complex string problems. These solutions include fast heuristic algorithms and advanced data structures, generally referred to as index structures. Although the importance of index structures is generally known to the bioinformatics community, the design and potency of these data structures, as well as their properties and limitations, are less understood. Moreover, the last decade has seen a boom in the number of variant index structures featuring complex and diverse memory-time trade-offs. This article brings a comprehensive state-of-the-art overview of the most popular index structures and their recently developed variants. Their features, interrelationships, the trade-offs they impose, but also their practical limitations, are explained and compared. PMID:22584621

    The Colorado Healthy Heart Solutions program uses community health workers to provide health promotion and navigation services for participants in medically underserved, predominantly rural areas who are at risk for developing cardiovascular disease. A text messaging program designed to increase participant engagement and adherence to lifestyle changes was pilot tested with English- and Spanish-speaking participants. Preimplementation focus groups with participants informed the development of text messages that were used in a 6-week pilot program. Postimplementation focus groups and interviews then evaluated the pilot program. Participants reported a preference for concise messages received once daily and for positive messages suggesting specific actions that could be feasibly accomplished within the course of the day. Participants also consistently reported the desire for clarity in message delivery and content, indicating that the source of the messages should be easy to recognize, messages should state clearly when participants were expected to respond to the messages, and any responses should be acknowledged. Links to other websites or resources were generally viewed as trustworthy and acceptable, but were preferred for supplementary material only. These results may inform the development of future chronic disease management programs in underserved areas or augment existing programs using text messaging reinforcement. PMID:25586133

    2010-01-01

    Background Psychological distress is common among medical students but manifests in a variety of forms. Currently, no brief, practical tool exists to simultaneously evaluate these domains of distress among medical students. The authors describe the development of a subject-reported assessment (Medical Student Well-Being Index, MSWBI) intended to screen for medical student distress across a variety of domains and examine its preliminary psychometric properties. Methods Relevant domains of distress were identified, items generated, and a screening instrument formed using a process of literature review, nominal group technique, input from deans and medical students, and correlation analysis from previously administered assessments. Eleven experts judged the clarity, relevance, and representativeness of the items. A Content Validity Index (CVI) was calculated. Interrater agreement was assessed using pair-wise percent agreement adjusted for chance agreement. Data from 2248 medical students who completed the MSWBI along with validated full-length instruments assessing domains of interest was used to calculate reliability and explore internal structure validity. Results Burnout (emotional exhaustion and depersonalization), depression, mental quality of life (QOL), physical QOL, stress, and fatigue were domains identified for inclusion in the MSWBI. Six of 7 items received item CVI-relevance and CVI-representativeness of ?0.82. Overall scale CVI-relevance and CVI-representativeness was 0.94 and 0.91. Overall pair-wise percent agreement between raters was ?85% for clarity, relevance, and representativeness. Cronbach's alpha was 0.68. Item by item percent pair-wise agreements and Phi were low, suggesting little overlap between items. The majority of MSWBI items had a ?74% sensitivity and specificity for detecting distress within the intended domain. Conclusions The results of this study provide evidence of reliability and content-related validity of the MSWBI. Further research is needed to assess remaining psychometric properties and establish scores for which intervention is warranted. PMID:20105312

    Understanding written or spoken language presumably involves spreading neural activation in the brain. This process may be approximated by spreading activation in semantic networks, providing enhanced representations that involve concepts that are not found directly in the text. Approximation of this process is of great practical and theoretical interest. Although activations of neural circuits involved in representation of words rapidly change in time snapshots of these activations spreading through associative networks may be captured in a vector model. Concepts of similar type activate larger clusters of neurons, priming areas in the left and right hemisphere. Analysis of recent brain imaging experiments shows the importance of the right hemisphere non-verbal clusterization. Medical ontologies enable development of a large-scale practical algorithm to re-create pathways of spreading neural activations. First concepts of specific semantic type are identified in the text, and then all related concepts of the same type are added to the text, providing expanded representations. To avoid rapid growth of the extended feature space after each step only the most useful features that increase document clusterization are retained. Short hospital discharge summaries are used to illustrate how this process works on a real, very noisy data. Expanded texts show significantly improved clustering and may be classified with much higher accuracy. Although better approximations to the spreading of neural activations may be devised a practical approach presented in this paper helps to discover pathways used by the brain to process specific concepts, and may be used in large-scale applications.

    Preventive maintenance is a core function of clinical engineering, and it is essential to guarantee the correct functioning of the equipment. The management and control of maintenance activities are equally important to perform maintenance. As the variety of medical equipment increases, accordingly the size of maintenance activities increases, the need for better management and control become essential. This paper aims to develop a new model for preventive maintenance priority of medical equipment using quality function deployment as a new concept in maintenance of medical equipment. We developed a three-domain framework model consisting of requirement, function, and concept. The requirement domain is the house of quality matrix. The second domain is the design matrix. Finally, the concept domain generates a prioritization index for preventive maintenance considering the weights of critical criteria. According to the final scores of those criteria, the prioritization action of medical equipment is carried out. Our model proposes five levels of priority for preventive maintenance. The model was tested on 200 pieces of medical equipment belonging to 17 different departments of two hospitals in Piedmont province, Italy. The dataset includes 70 different types of equipment. The results show a high correlation between risk-based criteria and the prioritization list. PMID:25029522

    Background Temporal information detection systems have been developed by the Mayo Clinic for the 2012 i2b2 Natural Language Processing Challenge. Objective To construct automated systems for EVENT/TIMEX3 extraction and temporal link (TLINK) identification from clinical text. Materials and methods The i2b2 organizers provided 190 annotated discharge summaries as the training set and 120 discharge summaries as the test set. Our Event system used a conditional random field classifier with a variety of features including lexical information, natural language elements, and medical ontology. The TIMEX3 system employed a rule-based method using regular expression pattern match and systematic reasoning to determine normalized values. The TLINK system employed both rule-based reasoning and machine learning. All three systems were built in an Apache Unstructured Information Management Architecture framework. Results Our TIMEX3 system performed the best (F-measure of 0.900, value accuracy 0.731) among the challenge teams. The Event system produced an F-measure of 0.870, and the TLINK system an F-measure of 0.537. Conclusions Our TIMEX3 system demonstrated good capability of regular expression rules to extract and normalize time information. Event and TLINK machine learning systems required well-defined feature sets to perform well. We could also leverage expert knowledge as part of the machine learning features to further improve TLINK identification performance. PMID:23558168

    Image indexing, storage, and retrieval based on pictorial content is a feature of image database systems which is becoming of increasing importance in many application domains. Medical image database systems, which support the retrieval of images generated by different modalities based on their pictorial content, will provide added value to future generation picture archiving and communication systems (PACS), and can be used as a diagnostic decision support tools and as a tool for medical research and training. We present the architecture and features of I2C, a system for the indexing, storage, and retrieval of medical images by content. A unique design feature of this architecture is that it also serves as a platform for the implementation and performance evaluation of image description methods and retrieval strategies. I2C is a modular and extensible system, which has been developed based on object-oriented principles. It consists of a set of cooperating modules which facilitate the addition of new graphical tools, image description and matching algorithms. These can be incorporated into the system at the application level. The core concept of I2C is an image class hierarchy. Image classes encapsulate different segmentation and image content description algorithms. Medical images are assigned to image classes based on a set of user-defined attributes such as imaging modality, type of study, anatomical characteristics, etc. This class-based treatment of images in the I2C system achieves increased accuracy and efficiency of content-based retrievals, by limiting the search space and allowing specific algorithms to be fine-tuned for images acquired by different modalities or representing different parts of the anatomy.

    Throughout the history of East Asian medicine, different kinds of acupuncture treatment experiences have been accumulated in classical medical texts. Reexamining knowledge from classical medical texts is expected to provide meaningful information that could be utilized in current medical practices. In this study, we used data mining methods to analyze the association between acupoints and patterns of disorder with the classical medical book DongUiBoGam of Korean medicine. Using the term frequency-inverse document frequency (tf-idf) method, we quantified the significance of acupoints to its targeting patterns and, conversely, the significance of patterns to acupoints. Through these processes, we extracted characteristics of each acupoint based on its treating patterns. We also drew practical information for selecting acupoints on certain patterns according to their association. Data analysis on DongUiBoGam's acupuncture treatment gave us an insight into the main idea of DongUiBoGam. We strongly believe that our approach can provide a novel understanding of unknown characteristics of acupoint and pattern identification from the classical medical text using data mining methods.

    Study Objectives: To estimate the prevalence of and identify sociodemographic risk factors for sedative medication use in the general Canadian population, and to examine the association between sedative medication use and body mass index (BMI). Design: Cross-sectional study Setting: Canadian population Participants: Participants from the 1994-2003 Canadian national health surveys, the National Population Health Survey (NPHS) and the Canadian Community Health Survey (CCHS). For the 2003 CCHS, n = 134,072, ages 12-80+ years. Interventions: Not applicable Measurements and Results: The overall prevalence of sedative medication use in Canada in 2003 was 5.5%, having more than doubled since 1994. Notable rises in sedative medication use have occurred among men, non-elderly, and obese individuals. After adjusting for potential sociodemographic and health status confounders, including psychiatric comorbidities, the odds of sedative use were significantly greater among morbidly obese (BMI ? 35 kg/m2) men (OR = 1.89, 95%CI = 1.02-3.53) and underweight (BMI < 18.5 kg/m2) women (OR = 2.11, 95%CI = 1.26-3.53). Conclusions: The use of sedative medications has substantially risen among the general Canadian population, and among particular population subgroups. The greater odds of sedative medication use found among morbidly obese men may reflect the presence of underlying obstructive sleep apnea, which may in turn serve to explain in part the known relationship between sedative medications and mortality. The increase in sedative medications coupled with their known adverse health associations raises potential public health concerns. Citation: Vozoris NT; Leung RS.

    Off-label use of a drug occurs when it is used in a manner that deviates from its FDA label. Studies estimate that 21% of prescriptions are off-label, with only 27% of those uses supported by evidence of safety and efficacy. We have developed methods to detect population level off-label usage using computationally efficient annotation of free text from clinical notes to generate features encoding empirical information about drug-disease mentions. By including additional features encoding prior knowledge about drugs, diseases, and known usage, we trained a highly accurate predictive model that was used to detect novel candidate off-label usages in a very large clinical corpus. We show that the candidate uses are plausible and can be prioritized for further analysis in terms of safety and efficacy. PMID:24303308

    One of the main problems in the efficiency and efficacy of an organization is its structural issue. Organizational culture is also considered as an effective factor in the performance of many organizations. The main goal of the present study was to determine the relationship of Centralization and organizational culture and performance indexes in Teaching Hospitals affiliated to Tehran University of Medical Sciences. This correlation study was performed in the year 2007. The population studied consisted of 4408 personnel from 13 hospitals among whom 441 subjects were selected and studied via a class sampling method. Data was compiled using a check list concerning the evaluation status of Centralization and another form concerning performance indexes as well as Robbin's organizational culture questionnaire. Data were obtained from the subjects by self answering and analyzed by using descriptive statistical indexes, T- test and Fisher's exact tests. Among the organizational culture indexes of the hospitals studied, control and organizational identity was better as compared to others (mean=3.32 and 3.30). Concerning the extent of Centralization in the hospitals studied, 53.85 % and 46.15 % were reported to have upper and lower organizational Centralization, respectively. Mean ratio of surgical operations to inpatients was 40%, the mean rate of admissions per active bed was 60.83, mean bed occupancy coefficient was 70.79%, average length of stay was 6.96 days, and mean net death rate was 1.41%. No significant correlation was seen between Centralization degree, organizational culture and performance indexes in teaching hospitals Tehran university of medical sciences. (with 95% confidence interval). Due to the fact that first grade Teaching hospitals use board certified members, expert personnel, and advanced equipments and because of the limitation of patients choice and, the extent of Centralization and many organizational culture components have no significant correlation with performance indexes of these hospitals. Further research regarding structure is suggested in the future. PMID:21287467

    Background Distinguishing cases from non-cases in free-text electronic medical records is an important initial step in observational epidemiological studies, but manual record validation is time-consuming and cumbersome. We compared different approaches to develop an automatic case identification system with high sensitivity to assist manual annotators. Methods We used four different machine-learning algorithms to build case identification systems for two data sets, one comprising hepatobiliary disease patients, the other acute renal failure patients. To improve the sensitivity of the systems, we varied the imbalance ratio between positive cases and negative cases using under- and over-sampling techniques, and applied cost-sensitive learning with various misclassification costs. Results For the hepatobiliary data set, we obtained a high sensitivity of 0.95 (on a par with manual annotators, as compared to 0.91 for a baseline classifier) with specificity 0.56. For the acute renal failure data set, sensitivity increased from 0.69 to 0.89, with specificity 0.59. Performance differences between the various machine-learning algorithms were not large. Classifiers performed best when trained on data sets with imbalance ratio below 10. Conclusions We were able to achieve high sensitivity with moderate specificity for automatic case identification on two data sets of electronic medical records. Such a high-sensitive case identification system can be used as a pre-filter to significantly reduce the burden of manual record validation. PMID:23452306

  3. [The main sources of medieval Islamic medicine and the medical books translated into Turkish in the 10th century texts. Muslim scientists produced original medical works].

    PubMed

    Se?en, R

    1993-01-01

    Medieval Islamic medicine in the late Omeyad and early Abbasid periods was based on works translated from the Greek, Sanskrit, Persian, Nabatean and Syriac languages, combining their own experiences in medical practice with the knowledge obtained from these. The majority of sources translated were Greek works; among them, those of Hippocrates and Galen were used prominently. From the theoretical standpoint, medieval Islamic medicine was based on the principles determined by Hippocrates. On the other hand, translations in different fields of medicine were done by specialists in those fields, who also authored their own works. Among them are such well-known figures as Abu Bakr el-Razi, Ibn Sina and Ibn el-Nafis. Islamic medicine saw a brilliant development during the Ayyubid period: with the establishment of many hospitals, clinical medicine and practical experience gained importance. these hospitals were at the same time centres of medical education and training. It is also in this period that the first medical school of the Muslim world was set up in Damascus by Mühezzebüddin el-Dahvar (d. 1231). Medical literature in Turkish originated in the framework of Islamic culture, as was in other fields of science. Early medical works in Turkish were translated from Arabic and Persian in the beginning of the 13th century. Original works in Turkish started to be produced from the end of the 13th and beginning of the 14th centuries. The volume of Turkish medical literature increased considerably throughout the Ottoman period. This experience and the accumulation of references facilitated the acquisition of modern medical knowledge. This paper is an overview of thirteen major works on medicine which were translated into Turkish in the middle of the 15th century. PMID:11624884

    Objective To evaluate the impact of body mass index on the short-term prognosis of non-surgical critically ill patients while controlling for performance status and comorbidities. Methods We performed a retrospective analysis on a two-year single-center database including 1943 patients. We evaluated the impact of body mass index on hospital mortality using a gradient-boosted model that also included comorbidities and was assessed by Charlson’s comorbidity index, performance status and illness severity, which was measured by the SAPS3 score. The SAPS3 score was adjusted to avoid including the same variable twice in the model. We also assessed the impact of body mass index on the length of stay in the hospital after intensive care unit admission using multiple linear regressions. Results A low value (< 20kg/m2) was associated with a sharp increase in hospital mortality. Mortality tended to subsequently decrease as body mass index increased, but the impact of a high body mass index in defining mortality was low. Mortality increased as the burden of comorbidities increased and as the performance status decreased. Body mass index interacted with the impact of SAPS3 on patient outcome, but there was no significant interaction between body mass index, performance status and comorbidities. There was no apparent association between body mass index and the length of stay at the hospital after intensive care unit admission. Conclusion Body mass index does appear to influence the shortterm outcomes of critically ill medical patients, who are generally underweight. This association was independent of comorbidities and performance status.

    Elderly patients admitted to the hospital are at increased risk for both in-hospital and post-discharge mortality. Risk assessment models (RAMs) for in-hospital mortality are based mainly on physiological variables and a few laboratory data, whereas RAMs for late mortality usually include other domains such as disability and comorbidities. We aim to evaluate if a previous validated model for 1-year mortality (the Walter Score) would also work well in predicting in-hospital mortality. We retrospectively revised the medical records of patients admitted on our ward, from April to December, 2013. Data regarding gender, activities of daily living (ADLs), comorbidities, and routine laboratory tests were used to calculate a Modified Walter Score (MoWS). The main outcome measure was all cause, in-hospital mortality. The analysis involved 1,004 patients. Of these, 888 were discharged alive, and 116 (11.5 %) died during the hospitalization. The mean MoWS was 4.9 (±3.6) in the whole sample. Stratification into risk classes parallels with in-hospital mortality (Chi square for trend p < 0.001). When dichotomized, MoWS has a sensitivity of 97.4 % (95 % CI 92.1-99.3), and a specificity of 48.2 % (95 % CI 44.9-51.5) with a good prognostic accuracy (area under the ROC = 0.81; 95 % CI 0.78, 0.84). Subgroup analysis according to different age groups gives similar results. A simple RAM based on multiple domains, previously validated for predicting mortality of older adults within 1 year from the index hospitalization, can be useful at the moment of admission to Internal Medicine wards to accurately identify patients at low risk of in-hospital mortality.

    Documentation of the care delivered to hospitalized patients is a ubiquitous and important aspect of medical care. The majority of references to documentation and coding are based on the Centers for Medicare and Medicaid Services (CMS) Medicare Severity Diagnosis Related Group (MS-DRG) inpatient prospective payment system (IPPS). We educated the members of a clinical care team in a single department (neurosurgery) at our hospital. We measured subsequent documentation improvements in a simple, meaningful, and reproducible fashion. We created a new metric to measure documentation, termed the "normalized case mix index," that allows comparison of hospitalizations across multiple unrelated MS-DRG groups. Compared to one year earlier, the traditional case mix index, normalized case mix index, severity of illness, and risk of mortality increased one year after the educational intervention. We encourage other organizations to implement and systematically monitor documentation improvement efforts when attempting to determine the accuracy and quality of documentation achieved.

    Background. Nursing documentation has long traditions and represents core element of nursing, but the documentation is often criticized of being incomplete. Nursing diagnoses are an important research topic in nursing in terms of quality of nursing assessment, interventions, and outcome in addition to facilitating communication and continuity. Aim. The aim of this study was to explore the nurses' and nursing students' experiences after implementing free text format nursing diagnoses in a medical department. Method. The study design included educational intervention of free text nursing diagnoses. Data was collected through five focus group interviews with 18 nurses and 6 students as informants. The data was analyzed using qualitative content analysis. Results. The informants describe positive experiences concerning free text format nursing diagnoses' use and usefulness; it promotes reflection and discussion and is described as a useful tool in the diagnostic process, though it was challenging to find the diagnosis' appropriate formulation. Conclusion. Our findings indicate a valid usability of free text format nursing diagnoses as it promotes the diagnostic process. The use seems to enhance critical thinking and may serve as valuable preparation towards an implementation of standardized nursing diagnoses. Use and support of key personnel seem valuable in an implementation process.

    To evaluate the smoking and khat chewing habits in male Aden University medical students and correlate them with blood pressure (BP), body mass index (BMI), and year of training, we randomly selected 100 students of different levels of training and measured their BP, height, and weight, and evaluated their cigarette smoking and khat chewing habits. The mean age of the whole group was 31.8 years. The mean BMI was 23.24 with a range from 22.6 in the in first year medical students to 24.7 (4.4) in 5 th year medical students (P= 0.127). The mean SBP, DBP, and MBP were 120.35, 70.47 and 87.1 mmHg, respectively, and did not change over the years of training. Preva-lence of smoking increased from 20% to 40% and khat chewing from 35% to 90% over the 5 years of training (P= 0.0003). There was a tendency for positive correlation between age and weight, BMI and frequency of khat chewing, and BMI and MBP. We found high prevalence of smoking and khat chewing among the medical students at Aden University and their prevalence increases with student seniority with no significant changes in BMI, SBP, DBP or MBP. There was a weak positive correlation between BMI with SBP, MBP and frequency of Khat chewing. PMID:19736493

    2014-02-01

    Early detection of an impending cardiac or pulmonary arrest is an important focus for hospitals trying to improve quality of care. Unfortunately, all current early warning systems suffer from high false-alarm rates. Most systems are based on the Modified Early Warning Score (MEWS); 4 of its 5 inputs are vital signs. The purpose of this study was to compare the accuracy of MEWS against the Rothman Index (RI), a patient acuity score based upon summation of excess risk functions that utilize additional data from the electronic medical record (EMR). MEWS and RI scores were computed retrospectively for 32,472 patient visits. Nursing assessments, a category of EMR inputs only used by the RI, showed sharp differences 24 hours before death. Receiver operating characteristic curves for 24-hour mortality demonstrated superior RI performance with c-statistics, 0.82 and 0.93, respectively. At the point where MEWS triggers an alarm, we identified the RI point corresponding to equal sensitivity and found the positive likelihood ratio (LR+) for MEWS was 7.8, and for the RI was 16.9 with false alarms reduced by 53%. At the RI point corresponding to equal LR+, the sensitivity for MEWS was 49% and 77% for RI, capturing 54% more of those patients who will die within 24 hours. PMID:24357519

    Objectives: To explore the feasibility of using the National Library of Medicine's Unified Medical Language System (UMLS) Metathesaurus as the basis for a computational strategy to identify concepts in medical narrative text preparatory to indexing. To quantitatively evaluate this strategy in terms of true positives, false positives (spuriously identified concepts) and false negatives (concepts missed by the identification process). Methods: Using the 1999 UMLS Metathesaurus, the authors processed a training set of 100 documents (50 discharge summaries, 50 surgical notes) with a concept-identification program, whose output was manually analyzed. They flagged concepts that were erroneously identified and added new concepts that were not identified by the program, recording the reason for failure in such cases. After several refinements to both their algorithm and the UMLS subset on which it operated, they deployed the program on a test set of 24 documents (12 of each kind). Results: Of 8,745 matches in the training set, 7,227 (82.6 percent ) were true positives, whereas of 1,701 matches in the test set, 1,298 (76.3 percent) were true positives. Matches other than true positive indicated potential problems in production-mode concept indexing. Examples of causes of problems were redundant concepts in the UMLS, homonyms, acronyms, abbreviations and elisions, concepts that were missing from the UMLS, proper names, and spelling errors. Conclusions: The error rate was too high for concept indexing to be the only production-mode means of preprocessing medical narrative. Considerable curation needs to be performed to define a UMLS subset that is suitable for concept matching. PMID:11141514

  15. Resources for comparing the speed and performance of medical autocoders

    PubMed Central

    Berman, Jules J

    2004-01-01

    Background Concept indexing is a popular method for characterizing medical text, and is one of the most important early steps in many data mining efforts. Concept indexing differs from simple word or phrase indexing because concepts are typically represented by a nomenclature code that binds a medical concept to all equivalent representations. A concept search on the term renal cell carcinoma would be expected to find occurrences of hypernephroma, and renal carcinoma (concept equivalents). The purpose of this study is to provide freely available resources to compare speed and performance among different autocoders. These tools consist of: 1) a public domain autocoder written in Perl (a free and open source programming language that installs on any operating system); 2) a nomenclature database derived from the unencumbered subset of the publicly available Unified Medical Language System; 3) a large corpus of autocoded output derived from a publicly available medical text. Methods A simple lexical autocoder was written that parses plain-text into a listing of all 1,2,3, and 4-word strings contained in text, assigning a nomenclature code for text strings that match terms in the nomenclature. The nomenclature used is the unencumbered subset of the 2003 Unified Medical Language System (UMLS). The unencumbered subset of UMLS was reduced to exclude homonymous one-word terms and proper names, resulting in a term/code data dictionary containing about a half million medical terms. The Online Mendelian Inheritance in Man (OMIM), a 92+ Megabyte publicly available medical opus, was used as sample medical text for the autocoder. Results The autocoding Perl script is remarkably short, consisting of just 38 command lines. The 92+ Megabyte OMIM file was completely autocoded in 869 seconds on a 2.4 GHz processor (less than 10 seconds per Megabyte of text). The autocoded output file (9,540,442 bytes) contains 367,963 coded terms from OMIM and is distributed with this manuscript. Conclusions A public domain Perl script is provided that can parse through plain-text files of any length, matching concepts against an external nomenclature. The script and associated files can be used freely to compare the speed and performance of autocoding software. PMID:15198804

    2007-12-01

    The aim of this study was to determine whether an existing outcome measure, the Interstitial Cystitis Symptom and Problem Index (ICSI/ICPI), is a valid, reliable, and clinically relevant instrument to assess the sensory urinary symptoms in women with fibromyalgia syndrome (FM). Ninety women with American College of Rheumatology 90 FM and who had at least two sensory bladder symptoms participated in the study. All underwent urological screening to exclude lower urinary tract pathology. All participants completed the following: ICSI/ICPI, Fibromyalgia Impact Questionnaire (FIQ), Medical Outcome Study Short Form 36, King's Health Questionnaire (KHQ), and Vulval Symptom Assessment Scale. Assessment was made for internal consistency reliability, test-retest reliability, and concurrent validity. Factor analysis was used to assess the internal structure of the scale. Factor analysis displayed two separate components of symptom and problem combinations as distinct from the original ICSI/ICPI developed for the interstitial cystitis population. The eight items of the index configured differently and formed two subscales of a newly developed Fibromyalgia Bladder Index. The two subscales of this index include the Bladder Urgency and Pain Subscale and the Bladder Frequency and Nocturia Subscale. This index has high internal consistency reliability (Cronbach's alpha coefficient of 0.81), test-retest reliability showing intraclass correlation of 0.85, and high concurrent validity through correlations between the Fibromyalgia Bladder Index and the KHQ (0.735, p = 0.000) and the FIQ (0.433, p = 0.000). This more specific configuration of the ICSI/ICPI better reflects FM bladder symptomatology. The Fibromyalgia Bladder Index is a validated FM-specific instrument that captures information about the sensory bladder symptoms and their impact in this fibromyalgia population. This instrument should allow for better understanding and management of this important fibromyalgia-associated problem. PMID:17476564

    The Integrated Medical Model (IMM) is a probabilistic model that estimates medical event occurrences and mission outcomes for different mission profiles. IMM simulation outcomes describing the impact of medical events on the mission may be used to optimize the allocation of resources in medical kits. Efficient allocation of medical resources, subject to certain mass and volume constraints, is crucial to ensuring the best outcomes of in-flight medical events. We implement a new approach to this medical kit optimization problem. METHODS We frame medical kit optimization as a modified knapsack problem and implement an algorithm utilizing a dynamic programming technique. Using this algorithm, optimized medical kits were generated for 3 different mission scenarios with the goal of minimizing the probability of evacuation and maximizing the Crew Health Index (CHI) for each mission subject to mass and volume constraints. Simulation outcomes using these kits were also compared to outcomes using kits optimized..RESULTS The optimized medical kits generated by the algorithm described here resulted in predicted mission outcomes more closely approached the unlimited-resource scenario for Crew Health Index (CHI) than the implementation in under all optimization priorities. Furthermore, the approach described here improves upon in reducing evacuation when the optimization priority is minimizing the probability of evacuation. CONCLUSIONS This algorithm provides an efficient, effective means to objectively allocate medical resources for spaceflight missions using the Integrated Medical Model.

  8. New generic indexing technology

    1996-01-01

    There has been no fundamental change in the dynamic indexing methods supporting database systems since the invention of the B-tree twenty-five years ago. And yet the whole classical approach to dynamic database indexing has long since become inappropriate and increasingly inadequate. We are moving rapidly from the conventional one-dimensional world of fixed-structure text and numbers to a multi-dimensional world of variable structures, objects and images, in space and time. But, even before leaving the confines of conventional database indexing, the situation is highly unsatisfactory. In fact, our research has led us to question the basic assumptions of conventional database indexing. We have spent the past ten years studying the properties of multi-dimensional indexing methods, and in this paper we draw the strands of a number of developments together - some quite old, some very new, to show how we now have the basis for a new generic indexing technology for the next generation of database systems.

    The major objectives of this study were to provide a list of candidate antiaging medicinal herbs that have been widely utilized in Korean medicine and to organize preliminary data for the benefit of experimental and clinical researchers to develop new drug therapies by analyzing previous studies. “Dongeuibogam,” a representative source of the Korean medicine literature, was selected to investigate candidate antiaging medicinal herbs and to identify appropriate terms that describe the specific antiaging effects that these herbs are predicted to elicit. In addition, we aimed to review previous studies that referenced the selected candidate antiaging medicinal herbs. From our chosen source, “Dongeuibogam,” we were able to screen 102 terms describing antiaging effects, which were further classified into 11 subtypes. Ninety-seven candidate antiaging medicinal herbs were selected using the criterion that their antiaging effects were described using the same terms as those employed in “Dongeuibogam.” These candidates were classified into 11 subtypes. Of the 97 candidate antiaging medicinal herbs selected, 47 are widely used by Korean medical doctors in Korea and were selected for further analysis of their antiaging effects. Overall, we found an average of 7.7 previous studies per candidate herb that described their antiaging effects. PMID:25861371

The current demonstration database indexes over 150,000 computer science articles containing over 2 million citations. Searchable by keyword only, database returns feature several options. Users can review a list of citations to a given paper with links to the full text articles (Postscript or .pdf format), view related articles, and sign up to have new citations for selected articles emailed to them. In the future, users should also be able to review a dynamically created and continuously updated bibliography. Additional resources at the site include a collection of papers about citation indexing, digital libraries, Web analysis, and neural networks. Users may also submit papers to the database and subscribe to be notified when additional databases become available at the site.

    The advent of remote and wearable medical sensing has created a dire need for efficient medical time series databases. Wearable medical sensing devices provide continuous patient monitoring by various types of sensors and have the potential to create massive amounts of data. Therefore, time series databases must utilize highly optimized indexes in order to efficiently search and analyze stored data. This paper presents a highly efficient technique for indexing medical time series signals using Locality Sensitive Hashing (LSH). Unlike previous work, only salient (or interesting) segments are inserted into the index. This technique reduces search times by up to 95% while yielding near identical search results. PMID:23367072

  11. Lossy Text Compression Techniques

    NASA Astrophysics Data System (ADS)

    Palaniappan, Venka; Latifi, Shahram

    Most text documents contain a large amount of redundancy. Data compression can be used to minimize this redundancy and increase transmission efficiency or save storage space. Several text compression algorithms have been introduced for lossless text compression used in critical application areas. For non-critical applications, we could use lossy text compression to improve compression efficiency. In this paper, we propose three different source models for character-based lossy text compression: Dropped Vowels (DOV), Letter Mapping (LMP), and Replacement of Characters (ROC). The working principles and transformation methods associated with these methods are presented. Compression ratios obtained are included and compared. Comparisons of performance with those of the Huffman Coding and Arithmetic Coding algorithm are also made. Finally, some ideas for further improving the performance already obtained are proposed.

    1993-01-01

    In order that medical informaticians can create Open Systems for health care, they need to have a common language. Efforts in the 1980s at the National Library of Medicine to create a Medical Informatics Vocabulary (MIVoc) have been useful for document indexing purposes, but need to be continued and extended. The Committee of European Normalization Technical Committee 251 has created a project team for MIVoc, and that team has used both automatic and manual methods and referenced many sources in producing a vocabulary that has support from numerous experts in Europe. MIVoc has both a glossary and a tree structure. The glossary has about 250 terms with detailed definitions that include various explanations and pointers. One critical pointer is the semantic link to other terms in MIVoc from a which a tree-structure is inferred. The success of MIVoc clearly depends on its being used, which in the long run depends also on the vocabulary being maintained. PMID:10163824

  19. What happens to creative medical students?

    PubMed

    Gough, H G

    1976-06-01

    A psychometric index of creative potential was devised by relating test scores to ratings of creativity in samples of architects, engineers, mathematicians, psychologists, and research scientists. A correlation of .45 was obtained between scores on this index and the criterion ratings in the total initial sample of 350 men. The tests used to compute scores on the index were also available for 284 first-year medical students being studied as physicians in a longitudinal inquiry on speciality choice and location of practice. The mean creativity score of the medical students was higher than that for any of the other samples. Within the array of means for medical specialty groups, psychiatrists ranked first and internists second. Students who failed to complete medical school also scored high, suggesting that dropping out is not just a matter of poor academic potential or unsuitability for a career in medicine. PMID:1271437

  17. Text Mining for Neuroscience

    NASA Astrophysics Data System (ADS)

    Tirupattur, Naveen; Lapish, Christopher C.; Mukhopadhyay, Snehasis

    2011-06-01

    Text mining, sometimes alternately referred to as text analytics, refers to the process of extracting high-quality knowledge from the analysis of textual data. Text mining has wide variety of applications in areas such as biomedical science, news analysis, and homeland security. In this paper, we describe an approach and some relatively small-scale experiments which apply text mining to neuroscience research literature to find novel associations among a diverse set of entities. Neuroscience is a discipline which encompasses an exceptionally wide range of experimental approaches and rapidly growing interest. This combination results in an overwhelmingly large and often diffuse literature which makes a comprehensive synthesis difficult. Understanding the relations or associations among the entities appearing in the literature not only improves the researchers current understanding of recent advances in their field, but also provides an important computational tool to formulate novel hypotheses and thereby assist in scientific discoveries. We describe a methodology to automatically mine the literature and form novel associations through direct analysis of published texts. The method first retrieves a set of documents from databases such as PubMed using a set of relevant domain terms. In the current study these terms yielded a set of documents ranging from 160,909 to 367,214 documents. Each document is then represented in a numerical vector form from which an Association Graph is computed which represents relationships between all pairs of domain terms, based on co-occurrence. Association graphs can then be subjected to various graph theoretic algorithms such as transitive closure and cycle (circuit) detection to derive additional information, and can also be visually presented to a human researcher for understanding. In this paper, we present three relatively small-scale problem-specific case studies to demonstrate that such an approach is very successful in replicating a neuroscience expert's mental model of object-object associations entirely by means of text mining. These preliminary results provide the confidence that this type of text mining based research approach provides an extremely powerful tool to better understand the literature and drive novel discovery for the neuroscience community.

    NSDL National Science Digital Library

    The world's philosophical and religious traditions have found a fine home at the Internet Sacred Text Archive, which, as the homepage notes, is "a quiet place in cyberspace devoted to religious tolerance and scholarship." Working together with a number of colleagues and volunteers, JB Hare has compiled this vast archive of sacred and philosophical texts from a number of public-domain sources and placed them on the site. What makes the site so intriguing is that Hare has placed detailed information about the sources and standards that have been deployed for each separate project, which will be of great interest to scholars. While the entire site can be searched, there is much to be learned by looking through the topics listed on the main page, which range from Atlantis to Zoroastrianism. Each separate topic contains a number of accurately transcribed (and some times, translated) primary and secondary documents, such as first-hand collections of oral traditions. For persons looking for their own copy of the material contained on the site, a CD-ROM is available for purchase as well.

  10. TRMM Gridded Text Products

    NASA Technical Reports Server (NTRS)

    Stocker, Erich Franz

    2007-01-01

    NASA's Tropical Rainfall Measuring Mission (TRMM) has many products that contain instantaneous or gridded rain rates often among many other parameters. However, these products because of their completeness can often seem intimidating to users just desiring surface rain rates. For example one of the gridded monthly products contains well over 200 parameters. It is clear that if only rain rates are desired, this many parameters might prove intimidating. In addition, for many good reasons these products are archived and currently distributed in HDF format. This also can be an inhibiting factor in using TRMM rain rates. To provide a simple format and isolate just the rain rates from the many other parameters, the TRMM product created a series of gridded products in ASCII text format. This paper describes the various text rain rate products produced. It provides detailed information about parameters and how they are calculated. It also gives detailed format information. These products are used in a number of applications with the TRMM processing system. The products are produced from the swath instantaneous rain rates and contain information from the three major TRMM instruments: radar, radiometer, and combined. They are simple to use, human readable, and small for downloading.

  11. Ergito: Virtual Text

    NSDL National Science Digital Library

    Ergito's Virtual Text, started in 2000, was created to provide a more timely and interactive alternative to printed scientific textbooks at the undergraduate and graduate level. This still-developing Web site covers life science writ large, including molecular biology, cell biology, genetics, biochemistry, immunology, and so on. However, only a small number of features are available free of charge. The first chapter of the molecular biology module -- Genes are DNA -- is available for free, as is Great Experiments, a collection of essays written by authors who conducted original research that has contributed greatly to our understanding of molecular and cellular biology. Great Experiments has a recently added essay by 2001 Nobel Prize winner Paul Nurse, titled "The Discovery of cdc2 as the Key Regulator of the Cell Cycle." These essays are formatted just as the Virtual Text pages are, with downloadable figures, a glossary, an online note-taking feature (notes are automatically compiled with a summary of the essay), glossary, and more. Ergito will soon make available Techniques, another free feature offering descriptions of widely used experimental protocols. Even without free access to the larger body of material in this Web site, Ergito is a fantastic resource for learning about molecular and cellular biology. Users must complete a free registration process to access this Web site.

  12. Reception of Texts Database

    NSDL National Science Digital Library

    Created by the Reception of Texts Project at the Open University, this pilot database is designed to help practitioners of reception studies "address issues of performance with the same degree of rigour and attention to evidence which is expected in textual studies and to develop ways of documenting performance which recognise its cross disciplinary and creative dimensions." To that end, academics and students in classical studies, literature, theater studies, and related fields can use this database to search for information on the performances of Greek plays in the original and in adaptations, versions and translations in English from c.1970 to the present, and in the future, poetry in English which draws on Greek texts, myths, and images. The database offers nine search categories, each with a slightly different search format, some offering only a simple keyword search, others with multiple modifiers, and others with pull-down menus for browsing. With the exception of the Critical Works category, searches ultimately return a Production Details page which generally includes modern and original title, year, theater, dates of performance, company, and music, design, and general notes. A useful feature throughout the database is a Missing Information form, which allows users to submit additional or missing information about specific entries.

    Objective: The objective of this study was to assess relationships between body mass index (BMI) and comorbid conditions within a large sample of truck drivers. Methods: Commercial driver medical examination data from 88,246 commercial drivers between 2005 and 2012 were analyzed for associations between BMI, medical disorders, and driver certification. Results: Most drivers were obese (53.3%, BMI >30.0 kg/m2) and morbidly obese (26.6%, BMI >35.0 kg/m2), higher than prior reports. Obese drivers were less likely to be certified for 2 years and more likely to report heart disease, hypertension, diabetes mellitus, nervous disorders, sleep disorders, and chronic low back pain (all P < 0.0001). There are relationships between multiple potentially disqualifying conditions and increasing obesity (P < 0.0001). Morbid obesity prevalence increased 8.9% and prevalence of three or more multiple conditions increased fourfold between 2005 and 2012. Conclusions: Obesity is related to multiple medical factors as well as increasing numbers of conditions that limit driving certification. PMID:25710607

    College students responding to the Preferred Method of Study (PMOS) questionnaire explained how they approach reading a new textbook chapter for comprehension. Results indicated that a significant positive correlation exists between the number of passes a student makes at new textbook material and his/her college grade-point average. Women showed a significant preference for adopting a single method of study. Less than half of the students queried construct organizational tools such as outlines or diagrams as they study a textbook. Students said they would alter their textbook strategies in response to the type of test they expected significantly more often than they would for the type of subject matter being studied. Only 6% of the students said they make a conscious effort to link the new concepts in the text to prior knowledge. There was no discernable relationship between the study strategies undergraduate college students employ and their college grade level (freshman through senior).

  16. Medical marijuana.

    PubMed

    Marmor, J B

    1998-06-01

    Although many clinical studies suggest the medical utility of marijuana for some conditions, the scientific evidence is weak. Many patients in California are self-medicating with marijuana, and physicians need data to assess the risks and benefits. The only reasonable solution to this problem is to encourage research on the medical effects of marijuana. The current regulatory system should be modified to remove barriers to clinical research with marijuana. The NIH panel has identified several conditions for which there may be therapeutic benefit from marijuana use and that merit further research. Marijuana should be held to the same evaluation standards of safety and efficacy as other drugs (a major flaw in Proposition 215) but should not have to be proved better than current medications for its use to be adopted. The therapeutic window for marijuana and THC between desired effect and unpleasant side effects is narrow and is a major reason for discontinuing use. Although the inhaled route of administration has the benefit of allowing patients to self-titrate the dose, the smoking of crude plant material is problematic. The NIH panel recommended that a high priority be given to the development of a controlled inhaled form of THC. The presence of a naturally occurring cannabinoid-receptor system in the brain suggests that research on selective analogues of THC may be useful to enhance its therapeutic effects and minimize adverse effects.

    NSDL National Science Digital Library

    A collaboration among the World Economic Forum's Global Leaders for Tomorrow Environment Task Force, The Yale Center for Environmental Law and Policy, and the Columbia University Center for International Earth Science Information Network (CIESIN), the Environmental Sustainability Index (ESI) "is a measure of overall progress towards environmental sustainability, developed for 122 countries." The ESI is based on 22 core "indicators," each of which combines two to six variables for a total of 67 underlying variables. The idea is to create cross-national comparisons of environmental progress as part of an effort to foster a more analytically driven approach to environmental decision-making. The top-ranked nations were Finland, Norway, and Canada, with the US coming in at number eleven and the UK placing sixteenth. Visitors can view the rankings and download the full text of the 225-page report and a Powerpoint Presentation at the site. A spreadsheet of the ESI is promised for the near future.

    2005-07-01

    Diagnostic medical imaging is a fundamental part of the practice of modern medicine and is responsible for the expenditure of considerable amounts of capital and revenue monies in healthcare systems around the world. Much research and development work is carried out, both by commercial companies and the academic community. This paper reviews briefly each of the major diagnostic medical imaging techniques—X-ray (planar and CT), ultrasound, nuclear medicine (planar, SPECT and PET) and magnetic resonance. The technical challenges facing each are highlighted, with some of the most recent developments. In terms of the future, interventional/peri-operative imaging, the advancement of molecular medicine and gene therapy are identified as potential areas of expansion.

  12. Medical Telemetry

    NASA Technical Reports Server (NTRS)

    1978-01-01

    Telemetry is the process whereby physiological or other data is acquired by instruments, translated into radio signals and j sent to a receiving station where the signals are decoded and recorded. Extensively used in I space operations, it is finding new Earth applications, among them transmission of medical data between emergency vehicles and hospitals. For example, transmission of an electrocardiogram from an ambulance to a hospital enables a physician to read the telemetered EKG and advise ambulance attendants on emergency procedures. Central Medical Emergency Dispatch (CMED) operates as a regional emergency medical communications center for Cleveland, Ohio and Cuyahoga County. The CMED system includes radio and telephone communications from hospital-to-hospital and from ambulance-to-hospital, but for improved emergency life support CMED sought to add a county-wide telemetry capability. The problem was that there were only eight radio frequencies available for telemetry and there were more than 30 potential users in Cleveland alone. NASA's Lewis Research Center volunteered its expert assistance. The Center's engineers studied the systems of other telemetry using cities, surveyed area hospitals to assure compatibility of telemetry equipment, and advised what types of equipment would be needed in emergency vehicles and at the various hospitals. The Lewis plan suggested that CMED be designated the central coordinating agency for the Cuyahoga County system, monitoring all telemetry frequencies and, when requested, assigning one not in use or one to be used at a sufficient distance that it would create no interference problem.

    2008-01-01

    In this paper we present a profile-based approach to information filtering by an analysis of the content of text documents. The Wikipedia index database is created and used to automatically generate the user profile from the user document collection. The problem-oriented Wikipedia subcorpora are created (using knowledge extracted from the user profile) for each topic of user interests. The index databases of these subcorpora are applied to filtering information flow (e.g., mails, news). Thus, the analyzed texts are classified into several topics explicitly presented in the user profile. The paper concentrates on the indexing part of the approach. The architecture of an application implementing the Wikipedia indexing is described. The indexing method is evaluated using the Russian and Simple English Wikipedia.

    Analysis and classification of free text documents encompass decision-making processes that rely on several clues derived from text and other contextual information. When using multiple clues, it is generally not known a priori how these should be integrated into a decision. An algorithmic sensor based on Latent Semantic Indexing (LSI) (a recent successful method for text retrieval rather than classification) is the primary sensor used in our work, but its utility is limited by the {ital reference}{ital library} of documents. Thus, there is an important need to complement or at least supplement this sensor. We have developed a system that uses a neural network to integrate the LSI-based sensor with other clues derived from the text. This approach allows for systematic fusion of several information sources in order to determine a combined best decision about the category to which a document belongs.

    Molecular biology has become heavily dependent on biological knowledge encoded in expert curated biological databases. As the volume of biological literature increases, biocurators need help in keeping up with the literature; (semi-) automated aids for biocuration would seem to be an ideal application for natural language processing and text mining. However, to date, there have been few documented successes for improving biocuration throughput using text mining. Our initial investigations took place for the workshop on ‘Text Mining for the BioCuration Workflow’ at the third International Biocuration Conference (Berlin, 2009). We interviewed biocurators to obtain workflows from eight biological databases. This initial study revealed high-level commonalities, including (i) selection of documents for curation; (ii) indexing of documents with biologically relevant entities (e.g. genes); and (iii) detailed curation of specific relations (e.g. interactions); however, the detailed workflows also showed many variabilities. Following the workshop, we conducted a survey of biocurators. The survey identified biocurator priorities, including the handling of full text indexed with biological entities and support for the identification and prioritization of documents for curation. It also indicated that two-thirds of the biocuration teams had experimented with text mining and almost half were using text mining at that time. Analysis of our interviews and survey provide a set of requirements for the integration of text mining into the biocuration workflow. These can guide the identification of common needs across curated databases and encourage joint experimentation involving biocurators, text mining developers and the larger biomedical research community.

    Reeve, Lawrence H; Han, Hyoil; Brooks, Ari D

    2007-01-01

    BioChainSumm is a biomedical text summariser utilising concept chaining (called BioChain) to link semantically-related concepts within biomedical text together. The BioChain process is adapted from existing lexical chaining approaches which chain semantically-related terms rather than concepts. The BioChain concept chains are used to identify salient candidate sentences which are extracted to produce a summary of the biomedical text. The Unified Medical Language System Metathesaurus and Semantic Network semantic resources identify related biomedical concepts. BioChainSumm is evaluated using the ROUGE system along with several existing, publicly-available summarisers. Our results show BioChain provides a promising methodology for biomedical text summarisation. PMID:18402049

    The Medical Article Records System (MARS) developed by the Lister Hill National Center for Biomedical Communications uses scanning, OCR and automated recognition and reformatting algorithms to generate electronic bibliographic citation data from paper biomedical journal articles. The OCR server incorporated in MARS performs well in general, but fares less well with text printed in small or italic fonts. Affiliations are often printed in small italic fonts in the journals processed by MARS. Consequently, although the automatic processes generate much of the citation data correctly, the affiliation field frequently contains incorrect data, which must be manually corrected by verification operators. In contrast, author names are usually printed in large, normal fonts that are correctly converted to text by the OCR server. The National Library of Medicine"s MEDLINE database contains 11 million indexed citations for biomedical journal articles. This paper documents our effort to use the historical author, affiliation relationships from this large dataset to find potential correct affiliations for MARS articles based on the author and the affiliation in the OCR output. Preliminary tests using a table of about 400,000 author/affiliation pairs extracted from the corrected data from MARS indicated that about 44% of the author/affiliation pairs were repeats and that about 47% of newly converted author names would be found in this set. A text-matching algorithm was developed to determine the likelihood that an affiliation found in the table corresponding to the OCR text of the first author was the current, correct affiliation. This matching algorithm compares an affiliation found in the author/affiliation table (found with the OCR text of the first author) to the OCR output affiliation, and calculates a score indicating the similarity of the affiliation found in the table to the OCR affiliation. Using a ground truth set of 519 OCR author/OCR affiliation/correct affiliation triples, the matching algorithm is able to select a correct affiliation for the author 43% of the time with a false positive rate of 6%, a true negative rate of 44% and a false negative rate of 7%. MEDLINE citations with United States affiliations typically include the zip code. In addition to using author names as clues to correct affiliations, we are investigating the value of the OCR text of zip codes as clues to correct USA affiliations. Current work includes generation of an author/affiliation/zipcode table from the entire MEDLINE database and development of a daemon module to implement affiliation selection and matching for the MARS system using both author names and zip codes. Preliminary results from the initial version of the daemon module and the partially filled author/affiliation/zipcode table are encouraging.

  14. Charging the Superconformal Index

    E-print Network

    Benjamin I. Zwiebel

    2012-03-14

    The superconformal index is an important invariant of superconformal field theories. In this note we refine the superconformal index by inserting the charge conjugation operator C. We construct a matrix integral for this charged index for N=4 SYM with SU(N) gauge group. The key ingredient for the construction is a "charged character," which reduces to Tr(C) for singlet representations of the gauge group. For each irreducible real SU(N) representation, we conjecture that this charged character is equal to the standard character for a corresponding representation of SO(N+1) or SP(N-1), for N even or odd respectively. The matrix integral for the charged index passes tests for small N and for N -> infinity. Like the ordinary superconformal index, for N=4 SYM the charged index is independent of N in the large-N limit.

    The general purpose of the MedIndEx (Medical Indexing Expert) Project at the National Library of Medicine (NLM) is to design, develop, and test interactive knowledge-based systems for computer-assisted indexing of literature in the MEDLINE® database using terms from the MeSH® (Medical Subject Headings) thesaurus. In conventional MEDLINE indexing, although indexers enter MeSH descriptors at computer terminals, they consult the thesaurus, indexing manual, and other tools in published form. In the MedIndEx research prototype, the thesaurus and indexing rules are incorporated into a computerized knowledge base (KB) which provides specific assistance not possible in the conventional indexing system. We expect such a system, which combines principles and methods of artificial intelligence and information retrieval, will facilitate expert indexing that takes place at NLM.

    Images are an integral part of medical practice for diagnosis, treatment planning and teaching. Image retrieval has gained in importance mainly as a research domain over the past 20 years. Both textual and visual retrieval of images are essential. In the process of mobile devices becoming reliable and having a functionality equaling that of formerly desktop clients, mobile computing has gained ground and many applications have been explored. This creates a new field of mobile information search & access and in this context images can play an important role as they often allow understanding complex scenarios much quicker and easier than free text. Mobile information retrieval in general has skyrocketed over the past year with many new applications and tools being developed and all sorts of interfaces being adapted to mobile clients. This article describes constraints of an information retrieval system including visual and textual information retrieval from the medical literature of BioMedCentral and of the RSNA journals Radiology and Radiographics. Solutions for mobile data access with an example on an iPhone in a web-based environment are presented as iPhones are frequently used and the operating system is bound to become the most frequent smartphone operating system in 2011. A web-based scenario was chosen to allow for a use by other smart phone platforms such as Android as well. Constraints of small screens and navigation with touch screens are taken into account in the development of the application. A hybrid choice had to be taken to allow for taking pictures with the cell phone camera and upload them for visual similarity search as most producers of smart phones block this functionality to web applications. Mobile information access and in particular access to images can be surprisingly efficient and effective on smaller screens. Images can be read on screen much faster and relevance of documents can be identified quickly through the use of images contained in the text. Problems with the many, often incompatible mobile platforms were discovered and are listed in the text. Mobile information access is a quickly growing domain and the constraints of mobile access also need to be taken into account for image retrieval. The demonstrated access to the medical literature is most relevant as the medical literature and their images are clearly the largest knowledge source in the medical field.

  13. The orifice revisited: women in gynaecological texts.

    PubMed

    Koutroulis, G

    1990-01-01

    A content analysis was carried out on obstetric and gynaecological textbooks recommended for medical students at four Australian universities. The texts were read for a hidden curriculum of sexist ideology. This study is a partial replication of a study carried out by Scully and Bart in the United States eighteen years ago. The findings of Scully and Bart demonstrated that obstetric and gynaecological texts contained outdated and erroneous views about women's sexuality and portrayed women in stereotyped roles. It was anticipated that institutionalized changes may have occurred since the time that Scully and Bart carried out their research and the texts would reflect this accordingly; particularly with the effect of the women's health movement which has been expressing dissatisfaction with the health care system. The findings of this research show that sexist ideology still pervades the obstetric and gynaecological texts, though to a lesser extent than eighteen years ago. There are some differences from what Scully and Bart discovered, but major similarities were found. The main difference between the results of this study and the findings of Scully and Bart, is that the majority of texts analysed here did not contain outdated and incorrect information about women's sexual response. For example, none of the texts refer to vaginal orgasm as the 'mature' response for women. The main similarity is that women's sexuality is still depicted with a heterosexual perspective, with marriage and mothering the 'natural' aspirations of all women. PMID:2331867

    As the amount of chemical literature increases, it is critical that researchers be enabled to accurately locate documents related to a particular aspect of a given compound. Existing solutions, based on text and chemical search engines alone, suffer from the inclusion of "false negative" and "false positive" results, and cannot accommodate diverse repertoire of formats currently available for chemical documents. To address these concerns, we developed an approach called Entity-Canonical Keyword Indexing (ECKI), which converts a chemical entity embedded in a data source into its canonical keyword representation prior to being indexed by text search engines. We implemented ECKI using Microsoft Office SharePoint Server Search, and the resultant hybrid search engine not only supported complex mixed chemical and keyword queries but also was applied to both intranet and Internet environments. We envision that the adoption of ECKI will empower researchers to pose more complex search questions that were not readily attainable previously and to obtain answers at much improved speed and accuracy.

    Modern medicine is an increasingly complex activity , based on the evidence ; it consists of information from multiple sources : medical record text , sound recordings , images and videos generated by a large number of devices . Medical imaging is one of the most important sources of information since they offer comprehensive support of medical procedures for diagnosis and follow-up . However , the amount of information generated by image capturing gadgets quickly exceeds storage availability in radiology services , generating additional costs in devices with greater storage capacity . Besides , the current trend of developing applications in cloud computing has limitations, even though virtual storage is available from anywhere, connections are made through internet . In these scenarios the optimal use of information necessarily requires powerful compression algorithms adapted to medical activity needs . In this paper we present a review of compression techniques used for image storage , and a critical analysis of them from the point of view of their use in clinical settings. PMID:23715317

  3. Injury narrative text classification using factorization model

    PubMed Central

    2015-01-01

    Narrative text is a useful way of identifying injury circumstances from the routine emergency department data collections. Automatically classifying narratives based on machine learning techniques is a promising technique, which can consequently reduce the tedious manual classification process. Existing works focus on using Naive Bayes which does not always offer the best performance. This paper proposes the Matrix Factorization approaches along with a learning enhancement process for this task. The results are compared with the performance of various other classification approaches. The impact on the classification results from the parameters setting during the classification of a medical text dataset is discussed. With the selection of right dimension k, Non Negative Matrix Factorization-model method achieves 10 CV accuracy of 0.93. PMID:26043671

    Solid state lasers are the real highlight of my talk today, and were really the star of the year. In every application area I can think of, people have tried with some success to introduce corturiercial solid state products. I'll go into more detail, but aside from solid state, a very significant event happened in Deceniber when one of the laser angioplasty companies (Advanced Interventional Systens) received FDA clearance to begin marketing the excimer for coronary applications (Figure 1) . This is the first time to my knowledge that an excimer has ever been cleared for a medical application in the United States. It's an event that we didn't really expect to happen so soon. It's extremely significant and we'll see where it goes from here. The system needs to be road-tested a bit but to get past the FDA is the major obstacle. Looking back to solid state laser the importance of solid state lasers is as researchers become more involved with the excimer and conduct more clinical studies in ophthalmology, they realize that it's not going to be a panacea for all refractive surgery or other ophthalmolic applications. In many cases it looks like the solid state laser may be the laser of choice in certain types of surgery; most notably perhaps in refractive surgery. We've all read about the success of the excimer at least in capturing the press's attention for corneal sculpting and vision correction. Well, it could be that actually the next generation will be a solid state laser, so let's keep an open mind here.

    The political battle over whether the recent drop in the medical care price index lessens or dramatizes the need for health reform is useless. In America's health care industry, prices are not meaningful, quality improvements go unmeasured, and relationships to other goods are distorted--all of which renders the medical care price index almost a worthless tool for policymakers. What the country needs is a new index, one that measures total health care spending. PMID:10132604

    The smallest integer t for which the Wilson loop W^{t} fails to exhibit area law is known as the confinement index of a given field theory. The confinement index provides us with subtle information on the vacuum properties of the system. We study the behavior of the Wilson and 't Hooft loops and compute the confinement index in a wide class of N=1 supersymmetric gauge theories. All possible electric and magnetic screenings are taken into account. The results found are consistent with the theta periodicity, and whenever such a check is available, with the factorization property of Seiberg-Witten curves.

    Automated analysis of unstructured text documents (e.g., web pages, newswire articles, research publications, business reports) is a key capability for solving important problems in areas including decision making, risk assessment, social network analysis, intelligence analysis, scholarly research and others. However, as data sizes continue to grow in these areas, scalable processing, modeling, and semantic analysis of text collections becomes essential. In this paper, we present the ParaText text analysis engine, a distributed memory software framework for processing, modeling, and analyzing collections of unstructured text documents. Results on several document collections using hundreds of processors are presented to illustrate the exibility, extensibility, and scalability of the the entire process of text modeling from raw data ingestion to application analysis.

    This paper presents a novel method for the analysis of nonlinear text quality in Chinese language. Texts produced by university students in China were represented as scale-free networks (word adjacency model), from which typical network features such as the in/outdegree, clustering coefficient and network dynamics were obtained. The method integrates the classical concepts of network feature representation and text quality series variation. The analytical and numerical scheme leads to a parameter space representation that constitutes a valid alternative to represent the network features. The results reveal that complex network features of different text qualities can be clearly revealed and applied to potential applications in other instances of text analysis.

    PubMed Central

    Kreel, L.

    1991-01-01

    There is now a wide choice of medical imaging to show both focal and diffuse pathologies in various organs. Conventional radiology with plain films, fluoroscopy and contrast medium have many advantages, being readily available with low-cost apparatus and a familiarity that almost leads to contempt. The use of plain films in chest disease and in trauma does not need emphasizing, yet there are still too many occasions when the answer obtainable from a plain radiograph has not been available. The film may have been mislaid, or the examination was not requested, or the radiograph had been misinterpreted. The converse is also quite common. Examinations are performed that add nothing to patient management, such as skull films when CT will in any case be requested or views of the internal auditory meatus and heal pad thickness in acromegaly, to quote some examples. Other issues are more complicated. Should the patient who clinically has gall-bladder disease have more than a plain film that shows gall-stones? If the answer is yes, then why request a plain film if sonography will in any case be required to 'exclude' other pathologies especially of the liver or pancreas? But then should cholecystography, CT or scintigraphy be added for confirmation? Quite clearly there will be individual circumstances to indicate further imaging after sonography but in the vast majority of patients little or no extra information will be added. Statistics on accuracy and specificity will, in the case of gall-bladder pathology, vary widely if adenomyomatosis is considered by some to be a cause of symptoms or if sonographic examinations 'after fatty meals' are performed. The arguments for or against routine contrast urography rather than sonography are similar but the possibility of contrast reactions and the need to limit ionizing radiation must be borne in mind. These diagnostic strategies are also being influenced by their cost and availability; purely pragmatic considerations are not infrequently the overriding factor. Non-invasive methods will be preferred, particularly sonography as it is far more acceptable by not being claustrophobic and totally free of any known untoward effects. There is another quite different but unrelated aspect. The imaging methods, apart from limited exceptions, cannot characterize tissues as benign or malignant, granulomatous or neoplastic; cytology or histology usually provides the answer. Sonography is most commonly used to locate the needle tip correctly for percutaneous sampling of tissues. Frequently sonography with fine needle aspiration cytology or biopsy is the least expensive, safest and most direct route to a definitive diagnosis. Abscesses can be similarly diagnosed but with needles or catheters through which the pus can be drained. The versatility and mobility of sonography has spawned other uses, particularly for the very ill and immobile, for the intensive therapy units and for the operating theatre, as well in endosonography. The appointment of more skilled sonographers to the National Health Service could make a substantial contribution to cost-effective management of hospital services. Just when contrast agents and angiography have become safe and are performed rapidly, they are being supplanted by scanning methods. They are now mainly used for interventional procedures or of pre-operative 'road maps' and may be required even less in the future as MRI angiography and Doppler techniques progress. MRI will almost certainly extent its role beyond the central nervous system (CNS) should the equipment become more freely available, especially to orthopaedics. Until then plain films, sonography or CT will have to suffice. Even in the CNS there are conditions where CT is more diagnostic, as in showing calculations in cerebral cysticercosis. Then, too, in most cases CT produces results comparable to MRI apart from areas close to bone, structures at the base of the brain, in the posterior fossa and in the spinal cord. Scintigraphy for pulmonary infarcts and bone metastases and in renal disease in children plays

    Automated processing, modeling, and analysis of unstructured text (news documents, web content, journal articles, etc.) is a key task in many data analysis and decision making applications. As data sizes grow, scalability is essential for deep analysis. In many cases, documents are modeled as term or feature vectors and latent semantic analysis (LSA) is used to model latent, or hidden, relationships between documents and terms appearing in those documents. LSA supplies conceptual organization and analysis of document collections by modeling high-dimension feature vectors in many fewer dimensions. While past work on the scalability of LSA modeling has focused on the SVD, the goal of our work is to investigate the use of distributed memory architectures for the entire text analysis process, from data ingestion to semantic modeling and analysis. ParaText is a set of software components for distributed processing, modeling, and analysis of unstructured text. The ParaText source code is available under a BSD license, as an integral part of the Titan toolkit. ParaText components are chained-together into data-parallel pipelines that are replicated across processes on distributed-memory architectures. Individual components can be replaced or rewired to explore different computational strategies and implement new functionality. ParaText functionality can be embedded in applications on any platform using the native C++ API, Python, or Java. The ParaText MPI Process provides a 'generic' text analysis pipeline in a command-line executable that can be used for many serial and parallel analysis tasks. ParaText can also be deployed as a web service accessible via a RESTful (HTTP) API. In the web service configuration, any client can access the functionality provided by ParaText using commodity protocols ... from standard web browsers to custom clients written in any language.

  14. Multiple 3D medical data watermarking for healthcare data management.

    2011-12-01

    The rapid development of healthcare information management for 3D digital medical libraries, 3D PACS, and 3D medical diagnosis has addressed the security issues pertaining to medical IT technology. This paper presents multiple watermarking schemes for a healthcare information management system for 3D medical image data for the protection, authentication, indexing, and hiding of diagnosis information. The proposed scheme, which is based on POCS watermarking, embeds a robust watermark for a doctor's digital signature and an information retrieval indexing key to the distribution of vertex curvedness; the scheme also embeds a fragile watermark for diagnosis information and an authentication reference message to the vertex distance difference. The multiple embedding process creates three convex sets for robustness, fragileness, and invisibility and projects the 3D medical image data onto these three convex sets alternately and iteratively. Experimental results confirmed that the proposed scheme has the robustness and fragileness to handle various 3D geometric and mesh modifiers simultaneously. PMID:20703760

    Research indicates that using a cell phone to talk or text while maneuvering a vehicle impairs driving performance. However, few published studies directly compare the distracting effects of texting using a hands-free (i.e., speech-based interface) versus handheld cell phone, which is an important issue for legislation, automotive interface design and driving safety training. This study compared the effect of speech-based versus handheld text entries on simulated driving performance by asking participants to perform a car following task while controlling the duration of a secondary text-entry task. Results showed that both speech-based and handheld text entries impaired driving performance relative to the drive-only condition by causing more variation in speed and lane position. Handheld text entry also increased the brake response time and increased variation in headway distance. Text entry using a speech-based cell phone was less detrimental to driving performance than handheld text entry. Nevertheless, the speech-based text entry task still significantly impaired driving compared to the drive-only condition. These results suggest that speech-based text entry disrupts driving, but reduces the level of performance interference compared to text entry with a handheld device. In addition, the difference in the distraction effect caused by speech-based and handheld text entry is not simply due to the difference in task duration. PMID:25089769

  7. Scene text deblurring using text-specific multiscale dictionaries.

    Texts in natural scenes carry critical semantic clues for understanding images. When capturing natural scene images, especially by handheld cameras, a common artifact, i.e., blur, frequently happens. To improve the visual quality of such images, deblurring techniques are desired, which also play an important role in character recognition and image understanding. In this paper, we study the problem of recovering the clear scene text by exploiting the text field characteristics. A series of text-specific multiscale dictionaries (TMD) and a natural scene dictionary is learned for separately modeling the priors on the text and nontext fields. The TMD-based text field reconstruction helps to deal with the different scales of strings in a blurry image effectively. Furthermore, an adaptive version of nonuniform deblurring method is proposed to efficiently solve the real-world spatially varying problem. Dictionary learning allows more flexible modeling with respect to the text field property, and the combination with the nonuniform method is more appropriate in real situations where blur kernel sizes are depth dependent. Experimental results show that the proposed method achieves the deblurring results with better visual quality than the state-of-the-art methods. PMID:25705915

  9. A diagnostic index for Down syndrome.

    PubMed

    Rex, A P; Preus, M

    1982-06-01

    We have made use of eight phenotypic findings of Down syndrome to develop an effective diagnostic index. We estimate that about 95% of patients who are suspected of having the syndrome can be categorized as having or not having it with 99.9% confidence. One can thereby make a fast clinical diagnosis on the majority of suspects before karyotyping is complete, allowing one to inform parents soon after birth and, in some instances, to make medical decisions about life-threatening defects. Furthermore, one can avoid the expense of chromosome studies on most patients who do not have the syndrome, unless there are other indications for chromosome studies. The eight features used in the index include three dermatoglyphic traits (hallucal and forefinger pattern, and palmar triradius), two measurements of physical traits (ear length and internipple distance), and three other clinical findings (Brushfield spots, wide-spaced first toe, and excess back neck skin).

    Text recycling, also referred to as self-plagiarism, is the reproduction of an author's own text from a previous publication in a new publication. Opinions on the acceptability of this practice vary, with some viewing it as acceptable and efficient, and others as misleading and unacceptable. In light of the lack of consensus, journal editors often have difficulty deciding how to act upon the discovery of text recycling. In response to these difficulties, we have created a set of guidelines for journal editors on how to deal with text recycling. In this editorial, we discuss some of the challenges of developing these guidelines, and how authors can avoid undisclosed text recycling. PMID:25127654

    The value of peak width at half-height for the illite 001 XRD reflection is known as the Kubler index or the illite "crystallinity' index. This measurement, which has been related to the degree of metamorphism of very low-grade, pelitic rocks, is a function of at least two crystal-chemical factors: 1) illite X-ray scattering domain size; and 2) illite structural distortions (especially swelling). Reynolds' NEWMOD computer program is used to construct a grid with which these two contributions to illite peak width can be determined independently from measurements of the 001 peak width at half-height and the Srodon intensity ratio. This method yields more information about changes undergone by illite during metamorphism than application of the Kubler index method alone. -Authors

Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Commercial web resources (Medscape, MedConnect, MedicineNet) add to the list of resource databases providing some of their content for open access. Several web-libraries (Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. Availability of specific dermatology-related websites (DermIs, DermNet, and Genamics Jornalseek) is useful addition to the ever growing list of web-based resources. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature and levels of detail available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine.

  12. C3-2: All-In-One: How Group Health Organizes Clinical Text from Clarity for Research

    PubMed Central

    Halgrim, Scott; Carrell, David; Tran, Diem-Thy

    2014-01-01

    Background/Aims Group Health Cooperative runs Epic as its Electronic Medical Record. The clinical text stored in Clarity, Epic’s relational reporting database, is valuable to research at Group Health Research Institute (GHRI). However, due to a number of factors, GHRI’s access to this data was limited. These factors included: 1) a limited window during the day allotted to GHRI due to higher priority reports on Group Health’s care delivery side, 2) Clarity splitting text notes into lines of about 5,000 characters, and 3) restrictions on managing the database itself, like adding a full-text index. We sought to make the clinical text more valuable for research by making it available at all times, combining all the content of a note into one record, and allowing for more database management options. Methods We have developed a nightly Python process that moves clinical text from four Clarity tables into one full-text-indexed table on our own server. In addition, we store metadata about each note--including note type, encounter date, department, and provider--in a parallel table. Results This conversion process, begun in 2010, converts about 60,000 notes per night and has converted every extant note in Group Health’s Clarity database for a total of 123 million notes as of October 2013. The notes’ availability has sped development of sophisticated NLP algorithms in the years since its inception. Another benefit is nightly automated status e-mails sent to the developers. When there was a recent import of several years of historical notes from legacy systems into Epic, GHRI knew immediately that a greater history of notes was available for research. Conclusions The text store at GHRI has strengthened research and grant submissions. Due to Clarity’s consistent data model and large footprint throughout the nation’s medical community, the solution should be easily transferable to other sites wishing to realize the same advantages. The solution is amenable to enhancement as needs arise for more metadata or for clinical text from other parts of Clarity. Remaining challenges are tracking changes to notes in Clarity and improving performance.

    The liability of a doctor as regards medical negligence is now a well accepted eventuality. However still many doctors and hospitals are unaware of their liability on account of negligence on the part of their junior doctors and hospital staff. Indemnity insurance specifically protects you against your liability to pay compensation including legal costs, fees or expenses. If court orders to pay compensation for negligence of patient and you have a valid insurance cover, the insurance company is supposed to pay the money. In the present text we are highlighting the medical practice related insurance such as personal indemnity insurance, error and omission policy for hospital and nursing homes and insurance policy related to damage to hospital building, damage to electrical and electronics appliances and also insurance for doctor's kit, signboard, burglary, fidelity guarantee and loss of money in transit.

  4. Why is Light Text Harder to Read Than Dark Text?

    NASA Technical Reports Server (NTRS)

    Scharff, Lauren V.; Ahumada, Albert J.

    2005-01-01

    Scharff and Ahumada (2002, 2003) measured text legibility for light text and dark text. For paragraph readability and letter identification, responses to light text were slower and less accurate for a given contrast. Was this polarity effect (1) an artifact of our apparatus, (2) a physiological difference in the separate pathways for positive and negative contrast or (3) the result of increased experience with dark text on light backgrounds? To rule out the apparatus-artifact hypothesis, all data were collected on one monitor. Its luminance was measured at all levels used, and the spatial effects of the monitor were reduced by pixel doubling and quadrupling (increasing the viewing distance to maintain constant angular size). Luminances of vertical and horizontal square-wave gratings were compared to assess display speed effects. They existed, even for 4-pixel-wide bars. Tests for polarity asymmetries in display speed were negative. Increased experience might develop full letter templates for dark text, while recognition of light letters is based on component features. Earlier, an observer ran all conditions at one polarity and then switched. If dark and light letters were intermixed, the observer might use component features on all trials and do worse on the dark letters, reducing the polarity effect. We varied polarity blocking (completely blocked, alternating smaller blocks, and intermixed blocks). Letter identification responses times showed polarity effects at all contrasts and display resolution levels. Observers were also more accurate with higher contrasts and more pixels per degree. Intermixed blocks increased the polarity effect by reducing performance on the light letters, but only if the randomized block occurred prior to the nonrandomized block. Perhaps observers tried to use poorly developed templates, or they did not work as hard on the more difficult items. The experience hypothesis and the physiological gain hypothesis remain viable explanations.

  5. Stemming Malay Text and Its Application in Automatic Text Categorization

    NASA Astrophysics Data System (ADS)

    Yasukawa, Michiko; Lim, Hui Tian; Yokoo, Hidetoshi

    In Malay language, there are no conjugations and declensions and affixes have important grammatical functions. In Malay, the same word may function as a noun, an adjective, an adverb, or, a verb, depending on its position in the sentence. Although extensively simple root words are used in informal conversations, it is essential to use the precise words in formal speech or written texts. In Malay, to make sentences clear, derivative words are used. Derivation is achieved mainly by the use of affixes. There are approximately a hundred possible derivative forms of a root word in written language of the educated Malay. Therefore, the composition of Malay words may be complicated. Although there are several types of stemming algorithms available for text processing in English and some other languages, they cannot be used to overcome the difficulties in Malay word stemming. Stemming is the process of reducing various words to their root forms in order to improve the effectiveness of text processing in information systems. It is essential to avoid both over-stemming and under-stemming errors. We have developed a new Malay stemmer (stemming algorithm) for removing inflectional and derivational affixes. Our stemmer uses a set of affix rules and two types of dictionaries: a root-word dictionary and a derivative-word dictionary. The use of set of rules is aimed at reducing the occurrence of under-stemming errors, while that of the dictionaries is believed to reduce the occurrence of over-stemming errors. We performed an experiment to evaluate the application of our stemmer in text mining software. For the experiment, text data used were actual web pages collected from the World Wide Web to demonstrate the effectiveness of our Malay stemming algorithm. The experimental results showed that our stemmer can effectively increase the precision of the extracted Boolean expressions for text categorization.

Particular attention is given to a statistically-based text analysis program that provides the knowledge base developer with a list of concept-specific phrases extracted from large textual corpora. Production and quality benefits resulting from the integration of machine aided indexing at CASI are discussed along with a number of secondary applications of NLD-derived systems including on-line spell checking and machine aided lexicography.

  9. Text Mining in Social Networks

    NASA Astrophysics Data System (ADS)

    Aggarwal, Charu C.; Wang, Haixun

    Social networks are rich in various kinds of contents such as text and multimedia. The ability to apply text mining algorithms effectively in the context of text data is critical for a wide variety of applications. Social networks require text mining algorithms for a wide variety of applications such as keyword search, classification, and clustering. While search and classification are well known applications for a wide variety of scenarios, social networks have a much richer structure both in terms of text and links. Much of the work in the area uses either purely the text content or purely the linkage structure. However, many recent algorithms use a combination of linkage and content information for mining purposes. In many cases, it turns out that the use of a combination of linkage and content information provides much more effective results than a system which is based purely on either of the two. This paper provides a survey of such algorithms, and the advantages observed by using such algorithms in different scenarios. We also present avenues for future research in this area.

    This paper questions different conceptions of Medical Humanities in order to provide a clearer understanding of what they are and why they matter. Building upon former attempts, we defend a conception of Medical Humanities as a humanistic problem-based approach to medicine aiming at influencing its nature and practice. In particular, we discuss three main conceptual issues regarding the overall nature of this discipline: (i) a problem-driven approach to Medical Humanities; (ii) the need for an integration of Medical Humanities into medicine; (iii) the methodological requirements that could render Medical Humanities an effective framework for medical decision-making.

  17. Rederivation of Dst Index

    NASA Astrophysics Data System (ADS)

    Svalgaard, L.

    2005-12-01

    Derivation of the Dst geomagnetic index involves removing the quiet diurnal variation (Sq) caused by thermal winds and tides in the ionosphere maintained by solar EUV radiation. The standard procedure has been to fit average, smoothed curves to the Sq computed from the five internationally quietest days of each month and to use these curves on all days to remove Sq from the observed values of the horizontal component of the geomagnetic field for three stations in the northern hemsphere and one station in the southern hemisphere, then to average the resulting values (weigthed by latitude) into a global Dst index. This procedure is problematic because 1) the day-to-day variability of the regular diurnal variation (Sr) is as large as the variation itself and 2) an annual variation of the level of horizontal component is not properly compensated for by using an unequal number of northern and southern stations. We show how these problems can be avoided by using only nighttime values and by using an equal number of stations in both hemispheres and calculate a new index Dsv back to 1930 (potentially back to 1900 or beyond). Using this new index, the long-term trend, semiannual variation, and average storm signature (superposed epoch around SSCs) are studied.

  3. Mass and Volume Optimization of Space Flight Medical Kits

    NASA Technical Reports Server (NTRS)

    Keenan, A. B.; Foy, Millennia Hope; Myers, Jerry

    2014-01-01

    Resource allocation is a critical aspect of space mission planning. All resources, including medical resources, are subject to a number of mission constraints such a maximum mass and volume. However, unlike many resources, there is often limited understanding in how to optimize medical resources for a mission. The Integrated Medical Model (IMM) is a probabilistic model that estimates medical event occurrences and mission outcomes for different mission profiles. IMM simulates outcomes and describes the impact of medical events in terms of lost crew time, medical resource usage, and the potential for medically required evacuation. Previously published work describes an approach that uses the IMM to generate optimized medical kits that maximize benefit to the crew subject to mass and volume constraints. We improve upon the results obtained previously and extend our approach to minimize mass and volume while meeting some benefit threshold. METHODS We frame the medical kit optimization problem as a modified knapsack problem and implement an algorithm utilizing dynamic programming. Using this algorithm, optimized medical kits were generated for 3 mission scenarios with the goal of minimizing the medical kit mass and volume for a specified likelihood of evacuation or Crew Health Index (CHI) threshold. The algorithm was expanded to generate medical kits that maximize likelihood of evacuation or CHI subject to mass and volume constraints. RESULTS AND CONCLUSIONS In maximizing benefit to crew health subject to certain constraints, our algorithm generates medical kits that more closely resemble the unlimited-resource scenario than previous approaches which leverage medical risk information generated by the IMM. Our work here demonstrates that this algorithm provides an efficient and effective means to objectively allocate medical resources for spaceflight missions and provides an effective means of addressing tradeoffs in medical resource allocations and crew mission success parameters.

  4. Locating and parsing bibliographic references in HTML medical articles.

    PubMed

    Zou, Jie; Le, Daniel; Thoma, George R

    2010-06-01

    The set of references that typically appear toward the end of journal articles is sometimes, though not always, a field in bibliographic (citation) databases. But even if references do not constitute such a field, they can be useful as a preprocessing step in the automated extraction of other bibliographic data from articles, as well as in computer-assisted indexing of articles. Automation in data extraction and indexing to minimize human labor is key to the affordable creation and maintenance of large bibliographic databases. Extracting the components of references, such as author names, article title, journal name, publication date and other entities, is therefore a valuable and sometimes necessary task. This paper describes a two-step process using statistical machine learning algorithms, to first locate the references in HTML medical articles and then to parse them. Reference locating identifies the reference section in an article and then decomposes it into individual references. We formulate this step as a two-class classification problem based on text and geometric features. An evaluation conducted on 500 articles drawn from 100 medical journals achieves near-perfect precision and recall rates for locating references. Reference parsing identifies the components of each reference. For this second step, we implement and compare two algorithms. One relies on sequence statistics and trains a Conditional Random Field. The other focuses on local feature statistics and trains a Support Vector Machine to classify each individual word, followed by a search algorithm that systematically corrects low confidence labels if the label sequence violates a set of predefined rules. The overall performance of these two reference-parsing algorithms is about the same: above 99% accuracy at the word level, and over 97% accuracy at the chunk level. PMID:20640222

    Background: Biomedical publications from a country mirror the standard of Medical Education and practice in that country. It is important that the performance of the health profession is occasionally documented. Aims: This study aimed to analyze the quantity and quality of biomedical publications from the Kingdom of Saudi Arabia (KSA) in international journals indexed in PubMed between 2008 and 2012. Materials and Methods: PubMed was searched for publications associated with KSA from 2008 to 2012. The search was limited to medical and biomedical subjects. Results were saved in a text file and later checked carefully to exclude false positive errors. The quality of the publication was assessed using Journal Citation Report 2012. Results: Biomedical research production in KSA in those 5 years showed a clear linear progression. Riyadh was the main hub of medical and biomedical research activity. Most of the publications (40.9%) originated from King Saud University (KSU). About half of the articles were published in journals with an Impact Factor (IF) of < 1, one-fourth in journals with no IF, and the remaining one-fourth in journals with a high IF (?1). Conclusion: This study revealed that research activity in KSA is increasing. However, there is an increasing trend of publishing in local journals with a low IF. More effort is required to promote medical research in Saudi Arabia. PMID:25657608

  6. Alex Catalog of Electronic Texts

    NSDL National Science Digital Library

    This catalog, maintained by Eric Lease Morgan, a systems librarian at North Carolina State University, specializes in American literature, English literature, and philosophy. Alex is particularly helpful because the search interface allows researchers to both look for documents and search the content of those documents. Users first search standard fields such as author, title, or publication date; then they can search the content of documents they select from their returns list. Though returns in content searches would be more convenient were they hyperlinked to the complete record for the text, such a search nonetheless has obvious utility for someone writing on, for example, flower imagery in Shakespearian sonnets or Emerson's vision of democracy. Another nice feature of the catalog is the ability to convert documents to .pdf files on-the-fly (with the font and spacing customizable). Alternately, users can download the whole collection of American or English literature or philosophy texts and the tools to search the texts.

  7. Discriminability measures for predicting readability of text on textured backgrounds

    Several discriminability measures were examined for their ability to predict reading search times for three levels of text contrast and a range of backgrounds (plain, a periodic texture, and four spatial-frequency-filtered textures created from the periodic texture). Search times indicate that these background variations only affect readability when the text contrast is low, and that spatial frequency content of the background affects readability. These results were not well predicted by the single variables of text contrast (Spearman rank correlation = -0.64) and background RMS contrast (0.08), but a global masking index and a spatial-frequency-selective masking index led to better predictions (-0.84 and -0.81, respectively). c2000 Optical Society of America.

    1998-04-01

    In this paper, we consider the problem of locating and extracting text from WWW images. A previous algorithm based on color clustering and connected components analysis works well as long as the color of each character is relatively uniform and the typography is fairly simple. It breaks down quickly, however, when these assumptions are violated. In this paper, we describe more robust techniques for dealing with this challenging problem. We present an improved color clustering algorithm that measures similarity based on both RGB and spatial proximity. Layout analysis is also incorporated to handle more complex typography. THese changes significantly enhance the performance of our text detection procedure.

    2012-01-01

    Marijuana has been used medically since antiquity. In recent years there has been a resurgence of interest in medical applications of various cannabis preparations. These drugs have been cited in the medical literature as potential secondary treatment agents for severe pain, muscle spasticity, anorexia, nausea, sleep disturbances, and numerous other uses. This article reviews the research literature related to medical applications of various forms of cannabis. Benefits related to medical use of cannabinoids are examined and a number of potential risks associated with cannabis use, both medical and recreational, are considered. There is a clearly identified need for further research to isolate significant benefits from the medical application of cannabinoids and to establish dosage levels, appropriate delivery mechanisms and formulations, and to determine what role, if any, cannabinoids might play in legitimate medical applications. It is also imperative to determine if reported dangers pose a significant health risks to users. PMID:22873011

    2015-05-01

    The medical-care sector often experiences changes in medical protocols and technologies that cause shifts in treatments. However, the commonly used medical-care price indexes reported by the Bureau of Labor Statistics hold the mix of medical services fixed. In contrast, episode expenditure indexes, advocated by many health economists, track the full cost of disease treatment, even as treatments shift across service categories (e.g., inpatient to outpatient hospital). In our data, we find that these two conceptually different measures of price growth show similar aggregate rates of inflation over the 2003-2007 period. Although aggregate trends are similar, we observe differences when looking at specific disease categories. PMID:24590759

    The patient’s medication history and status changes play essential roles in medical treatment. A notable amount of medication status information typically resides in unstructured clinical narratives that require a sophisticated approach to automated classification. In this paper, we investigated rule-based and machine learning methods of medication status change classification from clinical free text. We also examined the impact of balancing training data in machine learning classification when using the data from skewed class distribution. PMID:21347081

  11. Medieval Feminist Index

    NSDL National Science Digital Library

    The librarians and scholars who maintain the Medieval Feminist Index (MFI) compile citations for journal articles, book reviews, and essays relating to women, sexuality, and gender during the Middle Ages (450 CE to 1500 CE). Currently, MFI contains over 2500 citations from over 350 journals and essay collections, covering publications in English, French, German, and Spanish from 1994 through 1997. The entire MFI is searchable by title, author, subject, source, and date. In addition to these standard search fields, the descriptive indexing provides searchable fields for geographic region, century, and article type to facilitate detailed cross-field searches. Searching the MFI is quite simple, but users should note the following peculiarities: vague or allusive titles are appended with a summary sentence to enhance description; subject headings are controlled by a customized thesaurus, which can be viewed but not browsed; and some full citation records supply abstracts, but abstracts are not searchable by keyword.

    In intelligent analysis of large amounts of text, not any single clue indicates reliably that a pattern of interest has been found. When using multiple clues, it is not known how these should be integrated into a decision. In the context of this investigation, we have been using neural nets as parameterized mappings that allow for fusion of higher level clues extracted from free text. By using higher level clues and features, we avoid very large networks. By using the dominant singular values computed by Latent Semantic Indexing (LSI) and applying neural network algorithms for integrating these values and the outputs from other ``sensors,`` we have obtained preliminary encouraging results with text classification.

    2010-01-01

    Background The incidence of microscopic colitis (MC) is increasing, but its etiology remains unknown. Case reports and limited controlled data suggest that commonly prescribed drugs may be triggers. The aim of this study was to evaluate the prevalence of selected medication use [Proton pump inhibitors (PPIs), HMG-CoA reductase inhibitors (statins), and Selective serotonin reuptake inhibitors (SSRIs)] in patients with MC compared to ‘random controls’ and ‘diarrhea controls.’ Methods All patients were selected from primary care practices of a university health system during 2002 to 2007. Patients with biopsy proven lymphocytic or collagenous colitis were identified as cases. Diarrhea controls consisted of a 10:1 random sample of patients with chronic diarrhea and normal colon biopsies. Ten random controls were matched to each case on sex and index date (date of biopsy proven diagnosis). Drugs prescribed within the year prior to the index date were collected from the electronic medical record system. Results 26 cases (median age 68.9 yrs), 259 random, and 259 diarrhea controls were identified. The adjusted ORs for PPI, SSRI, and statin prescription within 12 months of diagnosis of MC between cases and diarrhea controls were 0.28 (0.07-1.07), 0.87 (0.28-2.64), 1.12 (0.34-3.71) respectively. Use of PPI and statins was less common in MC patients than in random controls (p<0.05 for both comparisons). Conclusions While prior data suggest that PPIs, statins, and SSRIs may be etiologically related to MC, our study found no increased association with these drugs. PMID:20640056

    In a multi-centre study, 745 patients undergoing internal medical rehabilitation (for hypertension, coronary heart disease, gastrointestinal and respiratory diseases) were investigated. The health economic benefit was evaluated during the 3 weeks of medical rehabilitation, during which a sleep-medical diagnostic work-up and treatment were applied. Ambulatory screening for sleep-related breathing disorders was carried out in all patients. In positive cases (Apnoea-Hypopnoea Index > or = 10) transfer to our sleep lab was recommended. 103 patients were found to be positive, of whom 47 attended the lab; 23 of these accepted nCPAP therapy, while 24 did not. The costs of the additional diagnosis and treatment were considered incremental costs--and the benefit identified as the decrease in days off work as revealed by a comparison of the year before with the year after rehabilitation. Days off work decreased by 38.4 days in the treated group, and increased by 25.4 days in the untreated group. The results were extrapolated to all patients in internal medical rehabilitation in Germany, and a cost-benefit analysis showed that the benefit of expanding the additional investigation to cover all patients would far exceed the incremental costs in the first year after rehabilitation by 58.26 Mio [symbol: see text] and in the second year by 81.15 Mio.

    We compute the index and associated spectral density for fluctuation operators which are defined via the Lagrangian of N=2 SQCD in the background of non-abelian confined multimonopoles. To this end we generalize the standard index calculations of Callias and Weinberg to the case of asymptotically nontrivial backgrounds. The resulting index is determined by topological charges. We conjecture that this index counts one quarter of the dimension of the moduli space of confined multimonopoles.

    Medical practice workplace etiquette is slowly being modified and fine-tuned. New workplace etiquette rules have become necessary because of advances in communications technology, shifting norms, and expectations of what constitutes good manners. Today's medical practice employees must concern themselves with traditional workplace manners but also the manners that come into play when they make or receive cell phone calls, text messages, and e-mails, and when they use social networking media outside of work. This article offers 25 rules for good manners in the medical practice that relate to the ways employees interact with people today, whether face-to-face or when using electronic communications technologies. It offers practical guidelines for making introductions both inside and outside the medical practice. This article also provides a self-quiz to help medical practice employees assess their workplace etiquette intelligence and 12 tips for good workplace table manners. PMID:20839511

    Medical images need to be transmitted with the patient's information without altering the image data. The present paper discusses secured indexing of lung CT image (SILI) which is a secured way of indexing the lung CT images with the patient information. Authentication is provided using the sender's logo information and the secret key is used for embedding the watermark into the host image. Watermark is embedded into the region of Noninterest (RONI) of the lung CT image. RONI is identified by segmenting the lung tissue from the CT scan image. The experimental results show that the proposed approach is robust against unauthorized access, noise, blurring, and intensity based attacks. PMID:26078782

  3. Replacing positivism in medical geography.

    PubMed

    Bennett, David

    2005-06-01

    Revisiting debates about philosophical approaches in medical geography suggests that logical positivism may have been prematurely discarded. An analysis of authoritative texts in medical geography and their sources in human geography shows that logical positivism has been conflated with Comtean positivism, science, empiricism, quantification, science politics, scientism and so on, to produce the "standard version" of the all-purpose pejorative "positivism", which it is easy to dismiss as an evil. It is argued that the standard version fails to do justice to logical positivism, being constructed on sources which are at some distance from the logical positivist movement itself. An alternative approach is then developed, an historically and geographically situated interpretation of logical positivism as a deliberately and knowingly constructed oppositional epistemology within an oppressive and anti-scientific culture predicated on idealist intuitionism. Contrasting the standard version with this alternative reading of logical positivism suggests that much may have been lost in human, and thus, medical geography, by throwing out the logical positivist baby with the "positivism" bath water. It is concluded that continuing to unpack the standard version of logical positivism may identify benefits from a more nuanced appreciation of logical positivism, but it is premature to take these to the level of detailed impacts on the kinds of medical geographies that could be done or the ways of doing them.

    This report responds to resolutions asking the American Medical Association (AMA) to develop recommendations for the use of medical equipment and technology onboard commercial airlines. Information for the report was derived from a search of the MEDLINE database and references listed in pertinent articles, as well as through communications with experts in aerospace and emergency medicine. Based on this information, the AMA Council on Scientific Affairs determined that, while inflight morbidity and mortality are uncommon, serious events do occur, which require immediate emergency care. Management of serious problems requires an integrated emergency response system that ensures rapid notification of medical personnel on the ground, assistance from appropriately trained flight crews and passenger volunteers (if available), and adequate medical supplies and equipment to stabilize the victim. Physicians have an important role in the preflight evaluation and counseling of potential passengers who are at risk of inflight medical complications, and in providing inflight medical assistance. Some U.S. and foreign air carriers are upgrading inflight emergency medical kits and placing automated external defibrillators aboard aircraft. Few data are available regarding the effectiveness of such improvements in improving health or survival outcomes. Recent federal legislation requires assessment of the extent of inflight medical emergencies, including the adequacy of emergency medical supplies and equipment carried onboard commercial airliners. This legislation also should alleviate liability concerns by providing immunity for physicians and others who render inflight medical assistance. PMID:10954361

The documents, which include an ESI press release, a ranking of countries, maps, and full ESI reports from 2000 to 2002, seek to provide in-depth details on the analytical framework, quantitative methodology, and data sources that underlie the ESI.

  9. Corpus of Electronic Texts (CELT)

    NSDL National Science Digital Library

    Developed at University College Cork, the Corpus of Electronic Texts project is intended "to bring the wealth of Irish literary and historical culture (in Irish, Latin, Anglo-Norman French, and English) to the Internet in a rigorously scholarly project." Additionally, the project is designed to be utilized by a wide group of interested parties, including students, academics, and the general public. Visitors may peruse the documents by language of original publication, or by viewing a complete list of all the works currently available (many in HTML or pdf format) from the project's website. Some of the rather compelling works available here include the complete works of Oscar Wilde, the political writings of Michael Collins, and various historical documents regarding the struggle for Irish independence.

    This paper proposes a Discriminative Semantic Feature (DSF) method for vector space model based text categorization. The DSF\\u000a method, which involves two stages, first reduces the dimension of the document vector space by Latent Semantic Indexing (LSI),\\u000a and then applies a Robust linear Discriminant analysis Model (RDM), which improves the classical LDA by a energy-adaptive\\u000a regularization criteria, to extract the

    Fake content is flourishing on the Internet, ranging from basic random word salads to web scraping. Most of this fake content\\u000a is generated for the purpose of nourishing fake web sites aimed at biasing search engine indexes: at the scale of a search\\u000a engine, using automatically generated texts render such sites harder to detect than using copies of existing pages.

    Investigations involving digital media (e.g., hard disks and USB thumb drives) rely heavily on text string searches. Traditional\\u000a search approaches utilizing matching algorithms or database technology and treebased indexing algorithms result in an overwhelming\\u000a number of “hits ” — a large percentage of which are irrelevant to investigative objectives. Furthermore, current approaches\\u000a predominantly employ literal search techniques, which lead to

  13. What is the coverage of SNOMED CT®on scientific medical corpora?

    This paper reports on the results of a large scale mapping of SNOMED CT on scientific medical corpora. The aim is to automatically access the validity, reliability and coverage of the Swedish SNOMED-CT translation, the largest, most extensive available resource of medical terminology. The method described here is based on the generation of predominantly safe harbor term variants which together with simple linguistic processing and the already available SNOMED term content are mapped to large corpora. The results show that term variations are very frequent and this may have implication on technological applications (such as indexing and information retrieval, decision support systems, text mining) using SNOMED CT. Naďve approaches to terminology mapping and indexing would critically affect the performance, success and results of such applications. SNOMED CT appears not well-suited for automatically capturing the enormous variety of concepts in scientific corpora (only 6,3% of all SNOMED terms could be directly matched to the corpus) unless extensive variant forms are generated and fuzzy and partial matching techniques are applied with the risk of allowing the recognition of a large number of false positives and spurious results.

  14. An ecology of text: using text retrieval to study alife on the net.

    Best, M L

    1997-01-01

    I introduce a new alife model, an ecology based on a corpus of text, and apply it to the analysis of posts to USENET News. In this corporal ecology posts are organisms, the newsgroups of NetNews define an environment, and human posters situated in their wider context make up a scarce resource. I apply latent semantic indexing (LSI), a text retrieval method based on principal component analysis, to distill from the corpus those replicating units of text. LSI arrives at suitable replicators because it discovers word co-occurrences that segregate and recombine with appreciable frequency. I argue that natural selection is necessarily in operation because sufficient conditions for its occurrence are met: replication, mutagenicity, and trait/fitness covariance. I describe a set of experiments performed on a static corpus of over 10,000 posts. In these experiments I study average population fitness, a fundamental element of population ecology. My study of fitness arrives at the unhappy discovery that a flame-war, centered around an overly prolific poster, is the king of the jungle. PMID:9654782

    The Solar Index, or, more completely defined as the Service Hot Water Solar Index, was conceptualized during the spring of 1978. The purpose was to enhance public awareness to solar energy usability. Basically, the Solar Index represents the percentage of energy that solar would provide in order to heat an 80 gallon service hot water load for a given location and day. The Index is computed by utilizing SOLCOST, a computer program, which also has applications to space heating, cooling, and heat pump systems and which supplies economic analyses for such solar energy systems. The Index is generated for approximately 68 geographic locations in the country on a daily basis. The definition of the Index, how the project came to be, what it is at the present time and a plan for the future are described. Also presented are the models used for the generation of the Index, a discussion of the primary tool of implementation (the SOLCOST program) and future efforts.

    Effective information retrieval from large medical hypertext systems will require a combination of browsing and full-text document retrieval techniques. Using a prototype hypertext medical therapeutics handbook, I discuss one approach to information retrieval problems in hypertext. This approach responds to a query by initially treating each hypertext card as a full-text document. It then utilizes information about document structure to

    Medication errors represent one of the most common causes of morbidity and mortality in hospitalized patients. Anesthesia has specific medication-related risks; providers must administer many potent intravenous medications quickly, often with minimal to no supervision. Well-described reasons for medication administration errors in anesthesia include medication ampoules with similar appearance and packaging, clinician inattention, ineffective communication, fatigue, and haste. Technologies that are used widely in other parts of the hospital, such as barcoding, are a challenge to implement in anesthesia, and systemic approaches, including color-coding of syringe labels and barcoding technology of syringes, have been evaluated with mixed results. Emphasis should be placed on implementing forcing functions when possible, utilizing technology, standardization, and education about the need for awareness in specific situations. More studies need to be done to define the epidemiology of medication errors in anesthesia, and more importantly, to assess interventions for preventing them. PMID:26062316

  18. Open Budget Index

    NSDL National Science Digital Library

    Around the world different governments provide different levels of information about their national budgets, and for some parties, this is a real area of concern. For those interested in this timely subject, the Center of Budget and Policy Priorities has created the Open Budget Index. Released in October 2006, this index rates countries on how open their budget books are to their citizens. As the site notes, this information can help a variety of groups "identify meaningful budget reforms needed in specific countries to combat corruption and strengthen basic services to improve people's lives." A great way to start on the site is by looking through country profiles from Uganda, Mexico, and India that will let concerned parties know specifically how budget transparency improves people's lives. After that, visitors can scroll down through a complete list of country summaries and questionnaires from Albania to Zambia. Visitors should also be aware that many of the materials on the site are available in a number of languages, including Arabic, French, Russian, and Spanish.

  19. Index Sets and Vectorization

    Vectorization is data parallelism (SIMD, SIMT, etc.) - extension of ISA enabling the same instruction to be performed on multiple data items simultaeously. Many/most CPUs support vectorization in some form. Vectorization is difficult to enable, but can yield large efficiency gains. Extra programmer effort is required because: (1) not all algorithms can be vectorized (regular algorithm structure and fine-grain parallelism must be used); (2) most CPUs have data alignment restrictions for load/store operations (obey or risk incorrect code); (3) special directives are often needed to enable vectorization; and (4) vector instructions are architecture-specific. Vectorization is the best way to optimize for power and performance due to reduced clock cycles. When data is organized properly, a vector load instruction (i.e. movaps) can replace 'normal' load instructions (i.e. movsd). Vector operations can potentially have a smaller footprint in the instruction cache when fewer instructions need to be executed. Hybrid index sets insulate users from architecture specific details. We have applied hybrid index sets to achieve optimal vectorization. We can extend this concept to handle other programming models.
